Noise Immune type of Antenna
 
Hi Paul,

Thank you for that information.

Also, thanks to everyone.

I found information on the T2FD antenna that was also recommended.

Hi,

way to lower power line noise, but unfortunately, the power lines run North to

East and West, which is what I want.

Hi, Brad.
My previous home was adjacent to a primary power distribution line
with three high voltage three phase lines, plus a residential
distribution line. Sometimes noise was fierce. I made a folded dipole
antenna out of 300 ohm TV twin lead, cut for the 75 meter ham band.
When first hooked to a receiver, I thought the receiver had died, but
eventually found a signal and it was working fine. Just no more noise
from the power lines.

If you can find a length of twin lead, try a folded dipole. I
currently use a horizontal loop antenna and it, too, is very low noise
pickup.
