I am not sure how to describe my aerial so I have attached a picture for you.(hope it comes through ok)Thanks again for your help.
That is a UHF aerial and does look in OK condition. Is the aerial pointing to the transmitter and is the polarity it aligned the correct way? Aerials are either horizontal or vertical polarity so the V shape reflector at the back will eiter be how it is now or be turned 90 degrees.
If it is all OK then I suspect you have a cabling issue.
dipper: Thanks for that, yes pointing directly at Sugarloaf. I will get up and alter the aerial to at rotate it to the other way. Once again many thanks for you assistance.
Yeah as sbiddle and wellygary have said, make sure it's orientated like everyone elses in your street and that the cable connections are nice and firm and clean.
There are some basic points to cover along the way. Make sure you're using good cable, where the middle core is a thick solid wire and there is lots of usually greasy silver braid sheilding around the outside. Make sure the contacts are clean, might even have to sand it a bit lightly to clean it up. What else is connected to this signal, like does it go to 5 other tv's/vcrs etc? How long does the cable run and are there any older amplifiers or odd boxes connected along the way? Might have to go investigate the ceiling etc!
The other thing is that some aerials were ok for the frequencies the normal/older analogue channels came on, but in some areas the newer digital channels are on frequencies quite a distance away from these. I'm sure there may be some places where the current uhf aerial simply doesn't receive much signal strength on the new frequencies being used. This despite the usual test that 'yes I get prime ok', if prime happens to be a fair way away from the newer digital channels.
I will get on the roof on the weekend and check all the connections and the cableThanks Again thanks to all for your advice
Best thing to do would be to take the Sky decoder and DVD recorder out of the circuit. It is likely that your problem is related to the RF modulated crap produced by either or both of these devices. Also, all fly leads should be RG6 with crimped F types (with necessary belling lee adapters as required). The roof is probably the last place to look.
