Antenna TV. Interference even comes in the form of passing/accelerating cars.

A compass needle is magnetic. It's attracted to anything that is magnetic .
Aerials are strange things indeed, in the 1950s I had
a friend who was into short wave/ham radio and he
was able to speak to people in Canada, USA, Australia
and many other places very clearly.

One day in daylight he showed me his aerial/antenna
set up, it was huge, in his garden/yard, he had copper
winding wire, the stuff that you make a motor with, he
had two tall poles of wood at the bottom of the garden,
two large insulated hooks at the corners of the house
and lots of loops of the wire around all of them, one I
would think was about 120 yards round and he seemed
to have hundreds of them, inside where the radio was he
had a piece of plastic or bakelite rod that again was wrapped
in copper wire, he said that you can't have too much antenna
and when he plugged the outside section into has regular
radio, the reception was fantastic, this in the days when the
static was part of every programme, yet his was clear.

So maybe we should go back in time and wrap the trees in
copper wire, at the back away from traffic!

Don't kid yourself. That wasn't a random wrapping of wire. It's scientifically designed to capture the frequencies he used to transmit and receive radio waves.
It was what is called a 'tuned' antenna.
 

Antenna amplifiers are of no use as far as I know because amplification works only from the transmitter. I read that a long time ago when I was trying to figure out a way to get signals from CBS an ABC.

They are actually o.k. if you are getting a signal without a lot of static.

There's not much point in amplifying a bad signal.
