How to Choose an External 4G or 5G Mobile Broadband Antenna

Saturday, Apr 11th, 2020 (12:01 am) - Score 221,072

Most of us are lucky enough to live within reach of a fairly strong UK mobile broadband (3G, 4G or 5G) network signal but that isn’t true everywhere, particularly in some remote rural areas. Sometimes the best way to receive a stronger signal is to try installing your own external antenna, but knowing what to get can be tricky.

Before we get started it’s important to clarify that this article is primarily intended for people who can’t access a good fixed line broadband ISP connection but may still be almost within reach of a viable mobile broadband alternative, albeit often struggling to get a good or stable signal from any of the operators. In this case you may benefit from an external antenna.

Obviously if you can already get a fast fixed line broadband ISP and just want a better indoor mobile signal then many of the operators already offer Femtocell style devices, which essentially plug into your home broadband connection (speeds of 0.5Mbps or 2Mbps+ are usually required) and use that to boost a localised mobile signal for your Smartphone.

Examples of Femtocell devices are Vodafone’s Sure Signal router, Three UK’s Home Signal , O2’s Boostbox or EE’s Signal Box device. Failing that some Smartphones and Apps from mobile network operators also support making calls on your allowance via home WiFi (some mobiles also have a more direct ‘WiFi Calling’ feature that does this without an app).

Let’s talk external antennas

The actual process of installing an external antenna is usually just a case of screwing one to the highest and most stable location possible outside of your house (e.g. a solid brick wall near your roof), pointing it in the right direction and then drilling the cable through into the house (making sure to avoid electrical cables, water pipes and sealing up afterwards etc.). Plenty of professional installers can do this for you too (often for sub-£100).

However as anybody who has ever tried to improve their mobile signal will probably attest, finding the right kit for the job isn’t simple and the variable nature of the radio spectrum – passing through different environments as it does – can result in all sorts of quirky outcomes. Sometimes the most logical solution doesn’t always turn out to be the right one for your specific location or needs.

Nevertheless our aim here is to provide some general guidance, but remember that sometimes it’s necessary to test a few different approaches before you decide upon the best one. In addition, we aren’t going to dare delve into the more industrial setups (e.g. personal mast construction or WiFi relays) as those are a bit too complex for most people, but if you’re surrounded by tall trees then sometimes it’s necessary to get radical.

Often it’s possible to buy a pole mounting and then fix your antenna on top of that (i.e. raised higher above your house) but just be sure that what you install is stable and won’t damage the house. Likewise in some areas a tall pole may breach planning rules, so always check with the local authority first.

Omni-directional or directional antenna

The first decision is whether or not to go with a directional or omni-directional antenna. A directional antenna will focus its higher gain (reception) in one direction, although it also becomes weaker in the other directions. By comparison omni antennas try to attract similar reception from all directions, albeit for a lower overall gain.

directional and omni-directional antenna

NOTE: Despite appearances above, direction and omni-directional antennas come in all sorts of different shapes and sizes. Sometimes they can even look the same.

On the surface you may think you know the answer to this one but it’s not always so simple. If you know where the nearest mast or base station for your operator is, particularly if you have LOS or Line-of-Sight (nothing in the way), then going directional might be the best choice (often true in rural areas). However a directional antenna can run into problems, such as if the station is congested or goes out of service (can occur during upgrades).

On the flip side an omni may result in better reliability because it’s looking at a wider area, although it can also attract more interference and may not deliver the same sort of performance as a well positioned directional. Generally if you’re not entirely sure where the mast is, or you live in an urban or suburban area, then an omni is probably the better choice. In fact start with an omni first anyway, it’s just easier.

NOTE: If you’re doing this DIY then an omni will be easier (less alignment hassle).

Now if you’re really feeling adventurous then you could install two antennas of different types but in order to make that work you’d have to connect them both to a MIMO configured router (two ports), such as the Huawei B618. Likewise you can also buy some MIMO antennas that have two outputs (MIMO 2×2) for related routers with two inputs. Just remember that this kind of kit tends to be more expensive and adds to the hassle of setup.

Generally it’s best to try with one antenna first and don’t bother buying a MIMO router with two external antenna ports if you’re only going to use an antenna with a single output, although if you do try installing two antennas then make sure to space them apart a bit.

At this point we should touch on polarisation. Mobile signals tend to be linearly polarised (they vibrate vertically, horizontally or a bit of both) and ideally the aim is to match the polarisation of your antenna to that of the signal (trial and error – helps if you can rotate the antenna). A quick solution to this is to go with a cross-polarised antenna, these usually have two outputs (good for MIMO routers), which can latch on to the signal regardless of its polarisation.

We’d also suggest keeping the cable between your antenna and router as short as possible in order to limit interference. Generally 5 metres or less should be fine, although some people have used more without problems but your mileage may vary (more cable usually equals greater signal loss). However, there are other factors that you need to consider too, so let’s move on.

What do the gain (dB / dBi) figures on an antenna mean?

The power of an antenna is measured by its “gain,” which is usually reflected in figures for either dBi (decibels relative to an isotropic radiator) or just dB (decibels relative to a dipole radiator – technically dBd but marketing folk often just use dB, which is confusing). The gain is essentially a relative measure of the antenna’s ability to direct (concentrate) radio frequency energy in a particular direction or pattern.

At this point the explanations can get very complicated and as this guide is directed toward people from all walks of life then we’ll simply say that the higher the gain, the better the antenna’s performance and range (over simplification). However antennas with very high gain may also be more expensive, often to reflect their quality, and so there’s something to be said for picking one in the middle ground (note that for every c.6dBi in gain, you could double the range of an antenna).

Some antennas may also give several different gain values to reflect the range of spectrum bands they support, as each may have different characterises due to the antenna design. As such it helps to know what bands your mobile operator is actually using and how to understand the different measures of signal strength (this will help when trying to identify unusual reception problems), which is what we’ll touch on next.

Maps and spectrum bands – finding the info.

One of the biggest challenges with setting up a new antenna is knowing where the signal comes from, how strong it is and which bands are being used in your local area (this can vary depending upon the operator). Vodafone, Three UK, O2 and EE (BT) all have coverage checkers on their websites but these are extremely vague and not always particularly accurate (see Ofcoms Mobile Coverage Checker).

    Is the tp-link AC1200 MR400 any good as a mobile router?

      I have the tp-link CD80 I bought it over a year ago in Malaysia I use it mainly when I travel. My reception an home is lousy with broadband especially at busy times.

      I now just buy a unlimited sim for £20 for 30 days it works fine for my needs and I have never had any problem at all.

      I was thinking of upgrading to a more up to date mifi and keep this one just for travel.

    Most available are illegal so beware.
    At thus time only Cel-Fi units are legal license free versions.
    We supply the commercial version for larger buildings and companies but hone versions do exist too.

    With mobile an external antenna is very much swings and roundabouts, as you often lose as much signal in the cable run as you gain from having the antenna external and high up. Much better to get a combined external modem/antenna, this means all the gains are present with an external antenna without the loses of the cable run or the often “black art” of co-ax connections and impedance matching, as the modem is optimally connected to the antenna with no losses of cabling, you then typically get your Internet from the external device as Ethernet.

      Thank you for this explanation, I always wondered why those aerial/lte modem combos were sold and what were the advantages, now I know 🙂

  7. Avatar photo Tim says:

    Good article Mark.

    One thing that was overlooked is cable loss and therefore the advantage of installing an external antenna that is also the modem. This negates the issue of signal loss between the antenna and the modem. This is really only a concern when the signal is poor/very poor.

    Mikrotik makes an LTE antenna + modem (all in one) that is very high gain and combines an LTE Cat6 modem. https://www.msdist.co.uk/mikrotik/wireless/lhg-lte6-kit

      That is a very interesting product as it is PoE as well.

      My only tiny concern would be lightening strikes hitting LAN devices. In my experience some kind of a WiFi/pure fibre gap is a good idea to mitigates the risk.

      On one setup we did use a very short piece (1m) of fibre between two routers. Obviously powered from desperate circuits.

    2. Avatar photo Back of Beyond Broadband says:

      Yes, we use these Mikrotik antenna and they’re great. They have a number of solutions and dual sim devices. The POE via CAT5/ 6 Is ideal and allows for the longer reach cable runs in the trickier spots.

    I have a holiday home in the South of France and also one in Southern Portugal. Both properties are in rural locations and suffer from very poor ADSL connections over the phone line, less than 4Mbps, which you also have to pay quite a high monthly fee for.

    So a couple of years ago I started researching 4G routers combined with external antennas. I now have a reliable 25Mbps connection via a 4G mast that’s 5kms away over a hill covered in forest.

    It’s turned into a bit of a hobby and I’ve been helping friends and neighbours with their internet connections. I’ve been providing them with a kit for less than 200 Euros that’s unlocked for any network, any SIM card.

    The kit I’m using is the Huawei 4G Router B315 or B310 combined with the WMM8G-7-27-5SP Antenna made by Panorama Antennas UK. I’ve installed approximately 50 of these kits, time and time again they’ve worked great and people are amazed at the connection speed they get.

    1. Avatar photo David says:

      There’s many 4G antennas on the market that promise fantastic performance and their specs look great, I’ve tried quite a few but unfortunately most of them don’t perform as promised.

      The antenna I’m using from Panorama Antennas works great and they also provide great customer support via telephone and email.

      No, I don’t work for them, I just think they offer a great product and service and deserve a mention!

    2. Avatar photo Mark says:

      Fully agree – there are a lot of antennas on Ebay and Amazon that make nonsense claims in terms physically impossible gain figures, so stick to a reputable supplier like Poynting or Panorama – they are more expensive, but do what they claim!

      Hi David, I live in a rural area and have a Huawei B525 router and looking to try and boost the 3/4g signal using an external antennae. What I am not clear on is how the external antennae connects to the router. There does not seem to be a socket on the router that would accept an external cable? I would appreciate any advice. Thanks very much.

      Hi David, just checked my router and noticed a compartment and ubcliped it and there are 2 sockets for external cables, I assume the external antennae has 2 cables and they just screw in? Is that to simple, inwonder if you might share an idiots DIY guide to installing the antennae. Thanks very much indeed, yours in hope.

      Opinion pieces published by them are opinions of the writer not the publication. That you don’t understand this basic premise speaks volumes.

  14. Avatar photo Jim Weir says:

    Couple of factual points in an otherwise good article.

    LTE requires a MiMo antenna by definition in the LTE standard, while using a single external antenna would work in some circumstances it would not provide any benefit. Always use a dual feed MiMo antenna.

    The best performing Antennas are Cross Polarised as this will March the base station antenna design – ie +45deg / -45deg rather than Vertical & Horizontal.

    RSSI isn’t relevant to LTE performance at all, only examine RSRP for a relative LTE signal “strength”, but it is relative to the band in use.

    For performance at any RSRP level the best performance will be governed by the SINR, critically the greater the number above 0dB (upto +20dB) the better the download and upload speed will perform.

    1. Avatar photo Mark says:

      Check out https://wiki.teltonika-networks.com/view/Mobile_Signal_Strength_Recommendations for an excellent in-depth but very readable summary of what all the numbers mean (particularly debunking RSSI as actually meaning anything useful at all if you have the more detailed numbers).

  15. Avatar photo Ian Hughes says:

    RSSI is a very crude measure of ‘signal strength’, as it lumps together signal, noise, interferers and reflections. Only signal is usable, hence sometimes poor performance with high RSSI level. Signal paths are not always reciprocal, due to receive and transmit being on different bands, so you may see high RSSI, but the Base site cannot see your transmissions nearly as well.

    Signal quality measures are better, but still don’t tell you how well the Base site is seeing your signals. In professional coverage assessment, we use real voice segments and make actual calls, scoring the received voice quality with a computer algorithm…

  16. Avatar photo Gary says:

    Great article, I researched externals before deciding on an integrated solution SXT LTE, Didn’t fancy spending the money on an external antenna for a 4g home router only to lose signal down the cabling from the antenna.

    Other option of course was to put the device in the Loft but then it would have needed mains power and be a pita to get to.

    Mines Poe and giving me better than 40x my old adsl connection. Sure its more variable depending on the cell tower congestion but haven’t regretted the switch to 4G. I’m classed as remote/rural/hard to reach so its really been a massive upgrade.

    it would also be interesting to see an article on the relative merits of different modems (apologies if I’ve missed a previous article)

    Should I get the ee sim + modem or buy my own modem and get a separate sim card?

    In my case, I am 2km with LOS to a mast which will hopefully be live within the next few months

      I’ve had excellent results with the Huawei B310 and B315, they’re pretty cheap too. If you want a bargain there’s many used, unlocked units for sale on Ebay.

      They seem to be very reliable, I’ve installed around 50 and haven’t had any faults at all.

      The internal antenna seems to work very well but of course there’s also the option of conection an external antenna. From what I’ve experienced theyre good at working with a weak 4G signal.

  18. Avatar photo GaryW says:

    I had a Huawei B618s modem in a ground floor window on the side of the house nearest our local EE 4G mast. Did a good job with its internal antenna but decided to try an external antenna anyway. Popped a Poynting A0002 directional antenna on our sky dish pole (which means it’s about 3m off the ground) and aligned using mast data and Google maps! Makes a significant difference to signal: RSRP is improved by about 6dBm, RSRQ stays more consitently in low single-digits, and SINR sits solidly at +/- 20dB (whereas before it would often dip down to 10dB). In terms of performance, download still seems to be limited more by congestion than anything else (can be well over 100Mbps at quiet times, but dips at peak times) although upload is noticeably better at 27-33 all the time versus low 20s. Biggest surprise was what happens on the occasions our nearest mast is down for maintenance and the modem switches to the next best mast which is in a different direction (NE rather than NNW). I’d expected to have to switch to internal antenna, but in fact in spite of being a directional antenna the Poynting gives the same stats and performance as the internal antenna used to! Just goes to show it’s art as well as science…

    1. Avatar photo Mark says:

      It’s worth looking at the gain profile diagrams that the more reputable producers include with their antennas. Although the Poynting A-002 is described as a directional unit, it has decent gain over quite an angle. I moved ours from indoor roof space (perfectly aligned on a pole) to outdoors flat against the side of building using the supplied wall mount (a few degrees off in alignment and about a metre lower), but the signal improved noticeably in both strength and quality.

Are there any IOS apps that can tell you where your signal is coming from?

At home in urban I have just ended up with a B315 (paddle aerials) in the loft Cat6 cabled down home router. Beware not all router firmware can be set to bridge mode so if that’s important spend carefully.

    I’ve supplied a number of 12v systems with an external antenna for people living on narrowboats, with great results.

    The kit I would recommend is as follows:

    Huawei B310 or B315 4G Router – Unlocked
    12v to 12v Regulated Power Adapter
    Panorama WMM8G-7-27-5SP Outdoor Antenna (same as the one in the photo at the very top of this article).

    The Huawei B310 and B315 are actually 12v DC units, they are supplied with a 240v AC power supply for use in homes.

    When a vehicle, motorhome, caravan, boat battery is being charged by an alternator, mains hook up, or solar power system, the 12v system can rise far higher than 12v, hence the reason why a regulated 12v power supply is required to avoid damage to the router.

      Hi Jamie One, are you actually going to be using it for 5G or only 4G? Consider what frequencies you need the antenna to cover.

      From my experience, If you’re willing to spend a little time aligning the antenna then the directional antenna will give better results than the omni-directional.

      I’ve never used either of those antennas, but I can strongly recommend an antenna from Panorama Antennas. http://www.panorama-antennas.com

      Are you sure the Huawei AF9E actually exists, I mean do Huawei actually make it? I can’t find it anywhere on Huawei’s websites.

      Yes, I’ve seen it on Amazon, eBay, etc. But I can’t find it on Huawei’s website, that’s why I’m wondering if it’s genuine? I might be wrong.

      You have to be careful as there’s many cheap or even expensive antennas coming from China that promise huge gain but actually don’t work very well.

All around my home I have excellent EE 4g but not inside (probably due to the heat reflective lining and glass) but the fixed broadband is terrible at 0.2mps. I bought a 4gee home router pre-owned on eBay (limited income) as the signal is good outside I figured I don’t need an amazing and expensive antenna what do you suggest?

    Thanks for this helpful article

      I would recommend this antenna, I’ve had great results with it.

      I’m not sure what router you have so you need to check if the connections are compatible.

      Panorama WMM8G-7-27-5SP Outdoor Antenna (same as the one in the photo at the very top of this article).

      Regards, David.

    My need is occasional but reliable mobile broadband for running Zoom meetings when away in my motorhome. When not zooming, I am happy with regular phone connections.

    Would it make sense to buy a battery powered unit and attach it to a pole which I can raise when I need to make the Zoom meetings?

    What might be the reasons not to do this? It seems a simple cheap solution.
    I had In mind the Huawei E5787. Why might I buy a more expensive unit?

    Any suggestions and comments welcome.

    Anyone have experience with the OutdoorRouter routers and antennas?

    Is it better with CAT6 than CAT4 when the LTE-connection is poor? Or is there no difference? CAT6 has higher MHz range.

    Thanks for answer!

      Most caravans are constructed with an aluminium skin, this kills the signal. You need to get a router that you can connect an external/outdoor antenna to.

      I would recommend a Huawei B310 or B315, they are resonably priced.

      Then attach an antenna made by Panorama Antennas and mount it outside.

      All the best, David.

    Excellent article! But I was wondering if there are any companies that offer professional installation? That can measure actual signal/speed from different base stations available, recommend best mobile operator for the area and install most suitable equipment.
