Help, I've just started to lose signal on most of the channels. I believe its the trees in the distance filling out with leaves in the summer. Where I live is a low area surrounded by hills. The direct path to the Darvel transmitter has trees on the horizon. KA3 5JL

It's been getting worse each year. Do I have to just give up on terrestrial tv and switch to satellite?

I have bought a high gain Group A aerial and a longer pole to put it on I already have a mast head amp on the current wideband aerial.

My question is am I just wasting money or can i improve it enough.

I did think about switching to the blackhill transmitter 45Km away. But that seemed ludicrous.

Any help appreciated

Grant: Darvel is coming up as the only transmitter predicted to cover your postcode, so I wouldn't expect much success with Black Hill. The Group A aerial on a longer pole may well improve things, but chances are the trees will cause the same problem again in the long run. You may well be better off installing Freesat, perhaps consider having a dish installed at the same time if you go ahead with replacing your existing aerial.

Grant :

Just firstly to mention, if you got a fatal error message when trying to post then ignore it, there's a bug in the site software, just wait several minutes to check if your post appears - they normally do.

Your locale is generally predicted to get good reception from Darvel. There are some spots that may get some sort of signal from Black Hill but it's likely to be unreliable, variable at best for the PSBs and poor for the COM multiplexes, so as mentioned by StepvensOnln1 I wouldn't expect success.

You mention reception has been getting worse each year, but no mention of how old your wideband aerial installation is. As you say that these trees are on the "horizon" so I'd be surprised if they were having that much of an impact. Any degradation of your existing aerial installation - water getting into the aerial connector or coax, masthead amp etc. to have a far greater impact. It's also possible the masthead amp may have degraded.

What sort of signal strength and quality figures (or BER/Error figures) are you getting in your TV tuning section for each UHF channel multiplex?

A Group A aerial is likely to perform better for you, but their gain will vary from make to make and model. You should make sure you replace all your coax with high quality double screened coax cable (eg.WF100 or equivalent).

All,
Thanks for the help I've gone for a YAGI 18 A band. on a longer pole replacing the cable outside while I fit. I will do this next week and see if this makes any difference. On the coverage map above it shows green all around a grey spot where my house is. I think therefore its possibly freesat for me if this fails.

Well, Thats the A group Aerial up and working 70% signal and 100% quality for most channels with the exception of COM 7 all the channels on Com 7 have gone. I've obviously misread that com 7 and 8 were moving to Channels 31 and 37. And Com 7 is still on Channel 55. Is it likely to move or will I just give up?

Grant: COM7 moved to UHF channel 55 as part of the 700MHz clearance, however it will be closing on 30th June when it's licence expires, so don't waste any time or effort on it. COM8 closed nearly two years ago, both were only ever intended to be temporary services.

Thanks for the info. Only channel ill miss is Quest HD. As you say its now gone anyway even if i still had the wideband.

Thank for the help. Its really usefull when trying to fathom freeview out. It would look like terestrial tv is being whittled down bit by bit.

Thank you
Grant
