Can anyone explain the constant sound being issued from the TV aerial which is at least audible to the east and whether this will be cleared soon. We are within half mile of the aerial- does it have a health warning?

Dirok:do you mean 'transmitter' not 'aerial' ? what transmitter in what area ?
What do you mean by 'noise' ? transmitters cannot and do not 'issue noises '
what do you mean by 'health warnings' ?
Overall a lot that makes no sense !

Dirok,
As Bernard stated, your post doesn't make much sense.
An Aerial can make a noise in the wind but the wind makes more noise so you wouldn't notice!
The transmitter mast's guy wires can also "whistle in the wind" but you'd have to be onsite to hear it.
I presume you're in Potton or on the Sandy heath above Sandy if you're 1/2 mile from the mast?
You will only require a small aerial or you may overload your receiver with too much signal.
As my brother say "You could pick up a signal on a bit of wet string up there" but I wouldn't recommend it!

Daniel: You haven't bothered with a postcode, so we can't find out if there is a problem with your transmitter, but its unlikely that a transmitter would lose 90% of its output for 5 days at not get noticed.
Logically, its your 'aerail', or at least something connecting your TV to it.
