1. Topband: 160m & 80m RFI issues requesting ideas for ANC4 sense antenna to cancell out local noise (score: 1): Author: "Goldtr8 $KD8NNU$" <goldtr8@charter.net>; Date: Sun, 1 Nov 2015 07:01:30 -0500; HI Guys, I have an intermittent RFI issue that comes from a subdivision about a 1/4 mile away. To combat the noise I have been trying to use my ANC4 and I built a sense antenna out of an 80m hamstick; /archives//html/Topband/2015-11/msg00000.html (9,473 bytes)

The vertical has s9 noise the others are 1/2 that level same as the KD8NNU If you are OK with vertical polarization, the simpl; /archives//html/Topband/2015-11/msg00003.html (8,846 bytes)

I have S9+ noise leverl on 160-30m. I used the MFJ version because I like the ability to control the gain on both sense and main antennas.
