My Mendips reception has totally disappeared. Several retunes have resulted in no signal at all. It was a 10 signal.

Pointing the ariel at Salisbury gets the usual poor picture..
Has the aerial group changed and thus I need a new aerial?

John Spillett: The William Hepburn's tropospheric ducting forecast chart currently shows that ducting could be affecting South Wales and Southwest England, with Devon and the Bristol Channel areas showing as the most likely to have TV and VHF radio reception affected by out of area signals.

See Tropospheric DX Modes for a discussion on Tropospheric Ducting and what causes it. It's a bit technical but worth wading though.

I seem to have a problem with my TV aerial. The aerial socket seems to have a loose connection. It's one of those sockets that's built into the house and I suspect that the cable connecting it to the aerial is the probably the original cable put in when the house was built in 1972. I think that the cable needs to be changed. In contrast, from ground level, the aerial seems to be in quite good condition and may be OK. What should I expect to pay a contractor to service my aerial system and change whatever is needed? How much more would a DAB aerial cost? What's the best way to find a reputable aerial fitter?

Charles Stuart: £150 seems to be average, and the 'rigging' part of this site might be of help.

For more info about aerials, etc (particularly if you want to do things yourself) - see A.T.V (Aerials And Television) FM DAB TV Aerial, plus poles and brackets (PE12QN)

Thanks. I think at £150 for a fitter to do it, I might see whether or not I can do it myself first. I have fitted an aerial before but in the loft.

I get my Freeview from Mendip in SN1 5LR and have received a card this morning to say I could be affected by the new 4G services. Unless I am misreading this site the 800 series has been cleared at Mendip and Seagry Court (where I could get a signal) is also clear.

Even more confusingly the 800 website doesn't mention Swindon as one of the areas they are writing to.

Have I lost the plot or have they?

Bob:
I received the same card this morning.
This is probably because some in Swindon are pointing towards Oxford that uses both Ch59+60.

So, no, you haven't lost the plot but some people in Swindon will be affected.
