Bilsdale Transmitter Fire Knocks Out TV, Radio and Mobile in Region

Wednesday, Aug 11th, 2021 (10:52 am) - Score 5,064
Bilsdale-Transmitter-on-Rural-Hill

A major fire at Arqiva’s (Cellnex) 315 metre tall Bilsdale Transmitter site in North Yorkshire (England) has knocked out TV and radio services for more than 1 million surrounding premises. On top of that, mobile (2G, 3G and 4G) services from O2, EE, Three UK and Vodafone have also been disrupted.

Admittedly, the impact upon mobile network services won’t be quite as severe since a lot of larger nearby communities will also be supported by smaller mast and rooftop sites. But it’s still a significant event for the wider area, especially those who live in smaller rural villages.

NOTE: The transmitter can be located via grid reference SE553962 or postcode TS97JS.

Most of the mobile operators could only say that they were aware of a problem in the area, although Three UK did offer a longer statement: “We’re sorry for any disruption you experience. Our engineers are working on masts nearby, which means the rest of our network is handling more traffic than usual.”

The fire, which appears to have been triggered by a lightning strike (not yet confirmed), began yesterday afternoon in a single-storey stone building and then spread to the transmitter mast – three other buildings on-site were unaffected. The North Yorkshire Fire and Rescue Service (NYFRS), which has since extinguished the blaze, are now concerned about the structural integrity of the mast. A 300m exclusion zone remains around the mast.

NYFRS Statement (Yesterday)

The initial call came at 13:19 from an engineer working at the transmitter, stating that he believed the mast was on fire due to smoke coming from below the first stay level (approximately 50 – 60 metres up). Calls were also received from members of the public who could see the smoke from some distance.

North Yorkshire Fire and Rescue Service worked to control the fire in difficult circumstances and extinguished a fire in a single-storey stone building and a 315ft transmitter mast. Only one building in a complex of four was affected and there are concerns about the structural integrity of the mast.

A 300m exclusion zone has been put in place around the mast.

Eight pumps from North Yorkshire Fire and Rescue Service attended the incident and firefighting has now ceased until the site has been confirmed as safe for further work.

The incident was attended by crews from Helmsley, Malton, Thirsk, Danby, Coulby Newham, Ripon, Northallerton and Acomb in addition to mobile water bowsers from Tadcaster and Boroughbridge.

NYFRS will be working on site tomorrow with Arqiva, the site operators, to bring the incident to safe conclusion.

A Spokesperson for the BBC said:

“TV and radio services are being disrupted in parts of North Yorkshire and Teesside following a fire at the Bilsdale transmitter. We’re in close contact with the company that runs the transmitter who are working on restoring services. For those in the affected area, BBC Radio Tees is still available on BBC Sounds and online, as are the BBC’s other radio stations. BBC TV can be viewed through BBC iPlayer and on cable and satellite platforms.”

Arqiva is understood to be moving temporary transmitter equipment to the site, although it’s unclear how long this will take to be deployed, and it seems unlikely to restore full service for all locals (the old mast did quite a big job). Credits to Steve for spotting.

      No, as far as we know, climate change believers had nothing to do with this.

    Cellnex did not takeover Arqiva, but they purchased their Telecoms division.

    Weather was dry & sunny yesterday afternoon up here, so probably not a lightning strike. Interestingly there was scheduled maintenance at Bilsdale this week. Maybe it didn’t quite go as planned?! I was around the Emley Moor area yesterday. Similar height to Bilsdale and it’s so “blummin”’ tall it totally dominates the landscape even from a few miles away.

      Hi Christopher, I live only a couple of miles away from this in Helmsley and I can confirm that there were very heavy downpours, sky black as night and heard what we assumed was thunder also from around lunchtime on Tuesday on and off part of afternoon.
      And both myself and hubbies very first thought when we heard of the fire was ….was it struck by lightening?

  4. Avatar photo Laura Balogh says:

    Not at all clear what the fire has damaged as seemingly only a single building was affected.
    Is it the transmitter equipment itself, RF amplifiers, the impedance matching circuitry ?
    Was this not already duplicated within redundant systems on-site ?
    Where do you get 100 kW temporary transmitter equipment ???
    And if the steel mast has been compromised, what happens then ?
    This transmitter provides terrestrial TV to a million people, tens of thousands of elderly with no other way to receive TV and radio. So a long term outage is really not socially acceptable.

      It appears the top of the mast was on fire in some pictures posted. Transmitters are always vulnerable to issues knocking millions of TVs off, its happened before and it has to be acceptable that complicated things go wrong sometimes. I think these days more fuss would have been made if Twitter goes down for 30 minutes than TV, but yes for some people it is all they have, but such is life, things go wrong.

      I’m sure they are working 24/7 to get something back on line, plus it doesn’t have to be at the same power level, they can get something temporary working on a lesser power level and give TV back to the vast majority.

      @phil – or was it smoke from the bottom going up the mast?

    3. Mark-Jackson Mark Jackson says:

      Smoke funnelled up from the ground station below, at least that’s what it looks like to me. Convection probably pulled it that way.

      @Mark Jackson

      Met Office chart showed no lightning strikes at the time in the area.

    5. Avatar photo Winston Smith says:

      A 315 metre metal mast at the top of a bare 360 metre hill would only last until the first thunderstorm if it dodn’t have lighting protection – which of course it does.

    Everyone doing agreat job to get things right and for disabled folk we are grateful. At 85 and 93 respectively tv and broadband is a huge miss. JB

  6. Avatar photo Nick Roberts says:

    Doesn’t say much about mobile-providers fall-back capability, OFCOM’s plan for same, or emergency service provision. Its all run on a commercial knife-edge.No defence in depth.

    Funny that we’re all supposed to be peer-to-peer networking in our working lives and yet the one piece of technology on which all are dependent is top-down stovepipe in design

    Perhaps the affected can while-away the late summer evenings lieing-back and counting the Star link satellites passing overhead.

    Some of the older generation will have sets with SW . . So World Service will be in reach – IMHO it has better programming than the parochial domestic carp

    1. Avatar photo Winston Smith says:

      Many residents of the North York Moors will be laughing at the idea of fall-back capability as they don’t have primary mobile signal, terrestrial TV or even satellite TV due to living in the shadow of large hills.

    2. Avatar photo 125us says:

      That’s because most British consumers buy only on price. In that model if you don’t do everything as cheaply as possible you go bust. Just look at all the comments on here from people who want investors to spend their money building out FTTP but then refuse to buy unless the product is priced at a point that no-one makes a return.

    3. Avatar photo Vince says:

      When you say “fall back” – you think the mobile networks should install so many transmission sites that they can overlap all coverage so if one mast has a problem, another one can cover the full area of the others and keep it going… that’s not going to happen for a million reasons.

      The good news is that someone thought of that and the terms explicitly tell you that it isn’t guaranteed as a service, so no problem as nobody is relying on it for mission critical stuff it was never designed for 🙂

    4. Avatar photo Vincent says:

      In terms of emergency services coverage, there are systems and processes in place for that – Tetra and the new ESN both have systems to get coverage to cover this sort of incident, so no big deal, it’s already a thing.

    I did work on the tower years ago,most probably a cable fire,some RF microwave Andrews cables are pressurised with a gas to improve dielectric properties

    Or generator fire,on UPS system?

    1. Avatar photo André says:

      Thank you for your post, I was wondering what it would be that could set a metal mast on fire… 🙂

  8. Avatar photo Justin says:

    1m may be somewhat overstated. Just over 0.5m premises in the Bilsdale geographical coverage area but many of those will receive TV services via other means such as Virgin and Sky in which case would impact additional TV’s in the home using Freeview through an aerial.

    I was alerted to this story yesterday
    from the Local Newspaper
    It started at around 1:30pm yesterday

    I do not know if there
    was any Lighting yesterday on the area
    Cause is yet to be determined I think

    Probably arking in the antenna cables after rain ingresion I supect …

    Totally coincidental, but I see Arqiva are currently looking to to divest themselves of the their UK TV tower business https://www.tvbeurope.com/business/arqiva-preparing-to-sell-uk-operations
