Hi
Postcode LL57 3TA house No 9 aerial mounted 15 foot from the ground on the rear wall.
I am using the Bethesda transmitter and my next door neighbour also uses the same but he is using a old BBC2 aerial set horizontally not vertically and pointing away from the transmitter (which is in direct line of site)by about 45 degrees at the Quarry he also gets the additional 27 channels I set my aerial the same retuned my TV and got the additional channels but with only a poor signal strength 30%, mounted vertically pointing directly at transmitter which is about 1 mile away the best signal I can get is 66% (with or without the booster) and when the wind blows or there is the slightest bit of rain or mist I lose the signal completely but my neighbours signal stays strong. I have even bought a new high gain aerial,booster and low loss cable but I still lose the signal. Any advise would be very helpful as I am fed up of going up and down a ladder every time the weather changes.
Thank You.

Lyndon Freeman: I realise that you have said you are using the Bethesda transmitter @ 1 mile / 257 degrees (V polarity) which uses mux channels 57 - 60 - 53, but though the Bethesda North transmitter @ 0.6 miles / 257 degrees (V polarity) is indicated as providing superior reception, it operating on mux Channels 28 - 25 - 22.

As far as your neighbour is concerned, what are these extra channels you refer to? as if he is managing to receive anything "extra" from the Llanddona transmitter @ 9 miles / 341 degrees (H) polarity then its purely through chance as its commercial channels are not indicated as being possible to receive at your location, the three commercial muxes being identified by being able to pick up ITV3 (10) - Pick TV (11) - Film 4 (15), and so does your neighbour receive any of those programme channels? these programme channels corresponding to mux channels 43 - 46 - 40.

The other point to note being that the PSB channels from Llanddona are single frequency with Bethesda i.e: 57 - 60 - 53 whereby making it difficult to know where you are picking the signal up from.

I will say though that your neighbours old BBC2 aerial aerial which might be a C/D type (identified by green plastic end plug on the elements horizontal support boom) would be better for Llanddona reception "if" your aerial is a group A type (red plastic end plug) which was installed for Bethesda North transmissions at the bottom end of the band, although if you reside in the end property with what looks like a flowering cherry tree in the garden then the two far end houses behind the metal gate could be blocking the signal from Llanddona, that is apart from the major block indicated on the terrain predictor at roughly 1 mile away from you.
