Typo to last post: UNPOWERED splitter

Craig:
The problem with unpowered splitters is that they seriously reduce the signal strength, to about 1/3rd for each of the two TV sets and assuming they are both plugged in. (1/3rd for each TV tuner and the other 1/3rd lost in the splitter.) If one TV is unplugged the results can be catastrophic as the 75 Ohm matching no longer occurs.
I would advise using a low gain powered splitter designed for 75 Ohm UHF TV use and good quality cables with well fitted plugs. These splitters generally 'isolate' the outputs from each other and there is no significant loss of signal strength, there may even be some gain so be careful not to have too much gain/signal strength. However, cheap splitters can create conditions for interference and/or poor signal quality on some of the signals but others may be unaffected.

Craig: An 18 element group A yagi would probably deliver a stronger signal and with a lower wind loading! Slight repositioning of the aerial might improve reception of C28 ie raising or lowering, or mounting a few inches to either side of the present location.

Dave Lindsay Thank you for your advice . It could be the Hemel Hempstead transmitter which is only four miles away . I didn't use this transmitter because it is unmanned and has been unreliable in the past . I will check the ITV HD station setting .

Thanks for your advice, we've tried a bit of repositioning but it didn't give us any better reception and we're already using foil shielded cable.

I'll explore having a look a new aerial or powered splitter. Would a masthead amplifier do the job (Product: procception proMHD12M - 10dB) with a mains amp within the flat?

Thanks

I am still managing with my old aerial (band A?) pointing at Sandy Heath, the recommended transmitter for my location (Knebworth), and get a good signal for the main channels but don't always get C48, C51, C52 stuff. Recently I have discovered I am recieving C22 stations (eg Movie Mix) (variable strength). Is this from Crystal Palace (???!!!) I wonder ? In which case it would surely indicate that my best bet is simply to turn my aerial around to point at Crystal Palace. Any thoughts ?

John V Osborne: If you aren't bothered about which regional programming you get then go with the tranmsitter that gives you the best reception.

You may get improved reception from Sandy Heath with an aerial that is more sensitive on 48, 51 and 52 - this being a wideband or even probably a Group K.

With your current aerial being a Group A one, then it is probably only suitable for receiving all channels from Crystal Palace, and as such rotating it might be your best bet.

Thank you. I have just tried manually tuning my set to C23 although a weak signal it has found all stations !!! Must be Crystal Palace despite being on the edge of their transmission range and my aerial pointing in the opposite direction ! Hate to think what will happen if I now do auto tuning ???
Cheers JVO
