Poor SINR on MIKROTIK LHGG LTE6 kit

I'm trying to set up MIKROTIK LHG series CAT6 LTE outdoor wireless router LHGG LTE6 kit.

I have line of sight 2miles to Vodafone mast & have good RSRP & RSRQ but poor SINR.

When I move the aerial & the RSRP & RSRQ go down the SINR goes up! Is this normal?

I've a 15m CAT6 ethernet cable that is routed past the house electric fuse board. Would this make a difference?

Any advice welcome.

Hi,

AFAIK RSRQ and SINR values are relative and depend on RSRP.. so if RSRP goes down so should RSRQ and SINR, though I am not very good at this.

How does this translate into speed changes?

Also, are you sure you are locking on to the right mast/cell?

The Ethernet cable shouldn't be affecting anything. CAT6 is good for 100m usually, doesn't suffer from losses like a coax would.

I'm getting 10Mpb/s which although similar to cable broadband in practice it is a lot slower.
Also getting up to 20Mpb/s upload!
 
We don't have much experience with Mikrotik here, but do try to play around with the bands, too. It often yields good results for Huawei users to force a certain band rather than go with the automatic settings.
 
Yep, we're Huawei guys on here, doesn't mean we can't have a go tho! I would advise the same as @Lucian if you can lock bands on mikrotik, im guessing you can as they are known for their extensive customisability.
 
@Pilgr1m ,

@Sdcampbell is reporting some good success with an Archer LTE router and external log periodics. While his circumstances may be very different from yours it's something you could try, if other options have failed.
Log periodic antennas have excellent directionality.

Did you ever get any improvement with the LHGG LTE6?

*ponders* I have an old 2m dish, would it work with the Mikrotik LDF and how could I get it up my radio tower! I think I'd have wind problems!

That's a big dish.. See if you can find something smaller, maybe a sky dish.

I have the same device and had exactly the same problem with decent upload but poor download. Locking to band 40 solved the problem for me. What band it is currently on?

It's got the same LTE6 modem as your LHG, you may be better off investing in a new cat12 or higher modem.

How long has that been happening and what ISP?
 
Just had another thought. When I got my LHG, it only had one metal clip/jaw, so I installed it in the top slot as I calculated that my mast is higher than the actual operator mast and it would be better to tip it down towards the horizon! I think I read somewhere it angled the dish by 5 degrees.

Does tipping it up or down affect the signal?
 
I was just out at my install, and wound down the extension part of the mast before deciding to abandon the idea because it is too wet. Just winding down the mast by about 6m has improved my RSRQ, with no chance to direction or anything else! Radio signals are so weird!

I always figured getting above all the hills and trees was the best thing to do!

If weather is anyway decent tomorrow I intend to take it down and remove the metal jaw and see what that does to the signal
