Chris.SE: The lead in the carport was about one foot infront of the trailer so no damage I checked the lead.I still have to change over the leads suggested by you.I forgot to mention when we first lost channel 8,,233, in bedroom and kitchen.I tried a retune no channels.Then one night about 2am I got up for a glass of milk.I thought I would just try a retune .Perfect all channels later the next day no 8 or 233.
After that we fitted the filters that are amps.Still no channels.My wife contacted Freeveiw they informed Channel 8 is on channel 35.(load of rubbish) .They then informed work is being carried out on the transmitter and I have to wait until work is completed.?? They did not have a clue.
Thank you

I agree that the Freeview helpline don't have much of a clue when it comes to technical stuff!!
The Local multiplex that carries London Live is on UHF channel C35. You could try a manual retune of C35 but whilst engineering work is going on, we don't know how it's affecting the signal for that multiplex.
LCN233, if you mean Sky News, that is on the ArqA/COM5 multiplex which is on UHF C22. Again we don't know how that signal is affected by the engineering work.
Here is what is usually an up-to-date list of which TV channels are carried on which multiplex -

You now mentioned that the splitters have amplifiers. What make/model are they?
All filters should be fitted on the input to an amplifier.

Hi,
I'm looking at getting an aerial and was told that I'd need a group A vertical polarised one for the crystal Palace transmitter?
My postcode is DA12 4AZ house number 63.
Would that be correct?
Thanks

Adrian : Crystal Palace is horizontally polarised, not vertical. Unless you're in an area with poor signal (you're predicted to receive a good signal) it's generally recommended to use a Group T or wideband aerial type which receives the whole UHF band (with a 700/800MHz filter to prevent interference from 4G/5G mobile services) such as a log periodic, rather than a grouped aerial.

Adrian :
In addition to the information from Steve, these days it is better that people use a Group K aerial.
This is effectively the new "wideband" for Freeview as it covers UHF channels 21-48 which are now the only ones in use in the UK. It also blocks the 700 & 800 MHz channels above 48 which helps eliminate potential interference from new/upgraded phone masts which will in many cases then not need a filter.
Group K Log periodics are available from some manufactures and a Group K Yagi from many.
