Arfon,is one of those more interesting Transmitter sites.
Origionally a VHF Band 3 TV transmitter,broadcasting ITV, HTV Wales on Channel 10, Horizontal polarization at 10KW.
A relay of Presely at that time.Commission date:9/11/62.
Then on 17/10/75,Arfon also started to Brodcast BBC 1/BBC 2/HTV Wales on channels
51/44/41 respectively,Vertical polarization on UHF.
According to the IBA at the time,this transmitter was broadcasting all TV channels at 3.6Kw,but in the BBC handbook at 3.5Kw. Up until the last listing of analogue Transmitters on the BBC website Arfon was then broadcasting at 4.2Kw?
Then i see your information showing that Arfon's analogue powers as being only 4 Watts!
What's the full story?
If you look at any other UHF Main/relay station,particularly during the UHF analogue era,transmitter powers were uniformed.
I 'cut my teeth'using this Transmitter for domestic installs well down the Cardigan coastline as far as Aberaeron/Tre-saith,where reception of both Blaenplwyf and Preseli was impossible.Ocassionally reception suffered from tidal fading,though mast head Amplifiers largely compensated for any losses.
Arfon also broadcasts Classic FM at 18.75Kw mixed pol and Heart?Cymru at 5Kw mixed pol on Band 2 VHF/FM.DAB:BBC/Digital 1 on Band 3 VHF.

The other interesting aspect of the Arfon TV transmitter is that it is well received on the East coast of Eire particularly in the Dublin and Wicklow areas.At 2Kw,i would imagine that DTT from Arfon is quite robust in these areas.

We pickup BBC, ITV, S4C, CH4 here in South Dublin (Shankill - D18) quite well (with a masthead amp)
curiously the HD broadcasts don't come in well at all - those channels were fine a couple of weeks ago but seemed to have dropped off now without trace which surprises me as these have the same power output as the SD channels.
Great to be able to pick up all those channels though!

Garret,It's quite possible that you are receiving a marginal signal from the Cairn Hill transmitter in the Irish Midlands which will cancel out the BBC B/HD Mux from Arfon,both on Channel 47.
Cairn Hill does stray into areas,south of Dublin and at 160Kw is an powerful transmitter.Erespective of different polarizations,between the two transmitters.
