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, 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. Paul, KD7HB |
