Freeview reception - all about aerials | Installing
Friday 24 February 2017 2:28PM

I erected a new aerial externally on a 2 meter pole on the roof, a Labgear SLx 48 Wideband High Gain aerial from Screwfix, with all new coax etc, plugged directly into back of TV, complete new installation, as I didn't previously have an aerial. However everything worked perfectly except I wasn't getting the HD channels or Film 4+1, nothing at all from C47 BBCB Mux.

After alot of reading and learning, I realized this aerial was probably to big for my location, and it was causing signal overload and that's why I wasn't getting the HD Channels C47 BBCB. So I've gone back to Screwfix and got the smallest aerial they do instead, which is a Labgear Mini Compact Log Periodic aerial with built in 4G filterig.

But I've still got the same problem, no BBCB C47.

TV diagnostics show all the other muxes as follows:
Channel 41: Signal Strength 93% Signal Quality 100%
Channel 44: Signal Strength 94% Signal Quality 100%
Channel 47: No Signal
Channel 56: Signal Strength 90% Signal Quality 100%
Channel 58: Signal Strength 90% Signal Quality 100%
Channel 60: Signal Strength 90% Signal Quality 100%

I've re-tuned and cleared the channel list from the TV numerous times, rechecked the cable and as I've said even got another aerial.

My Location is IP3 0LA number 138 and pointing at the Sudbury transmitter.

Is it still likely that the signal strength is to strong even with the smallest aerial I could get, and that I may actually need an attenuator instead?

Hi StevensOnln1, I'm glad I asked now, I wouldn't have suspected my TV was at fault as I've been receiving Sky+ HD without any problems through HDMI, but I've cancelled Sky and now got Freesat+ HD box (Humax HDR-1100S) instead, again no problem with 1080p HD on a HDMI lead from that either.

Plus I've erected an aerial to get the few channels not available on Freesat "Dave, Sony Movies, Quest" etc which I watch aswell, my TV is an LG 32LH3000 and it appears as if it may only have a DVB-T tuner and not DVB-T2. Unfortunately the original manual covers about 10 different TV's and it's hard to work out from reading that what the specs are.

But at What HiFi it's stating tuner DVB-T only.

Nothing about the tuner type in the specs at LG though.

Looks like I should have asked before getting another new aerial and going up on the roof again, ah well live and learn. And I think I might be right in thinking the Log Periodic Aerial is a better choice and more future proof anyway that I've now got up there. Even if it does look ridiculously small and incapable up on the roof, it seems to be performing really well signal wise.

StevensOnln1: Thanks for your help, I'm relieved to know that it's the TV tuner rather than a problem with the aerial. And I guess when I do replace my TV I'll be very careful to make sure a new one has a DVB-T2 tuner. Not in any immediate rush to do that yet though as the Humax Box has all the smart capability that I need at the moment anyway.

Thanks again.
