Re: [IRCA] Cable connectors



OK, one other thought...

The goal is to reduce the signal ingress on an antenna cable to the lowest possible level. What if the receive end was run through a transformer to open the ground connection. Then, a single wire was run parallel right next to the coax for the entire length. Then coupled out of phase with the shield on the coax itself? I have to wonder if that could be tweaked to drop the ingress signals by canceling them out? A 180 degree transformer keeps that phase over a wide frequency range so it wouldn't be a frequency-specific null.

The main reason I started this whole project is that the ingress spoiled any null I could get with two loops spread about 150' apart. Even the null of the loop itself was negligent. By clearing out the ingress, it may be possible to set two loops pretty far apart and positioned to null a pest. Then the two loops could be phased to deepen the null or even null a second pest on the same frequency.
