Lots of good info on some of these posts already. Although I like a pair of inline flag antennas terminated with VACTROLs separated by 100 feet inline better than the center feed/terminated design I saw earlier. Great F/B and tweakable remotely to make sure that F.B is maxedd at the frequency

Topband: NCC-2 remarks

I have one here and would not be able to do much on 160 without it. Patterns depend mostly on what antennas you hook to it. I have tried short verts, was not happy. Now use 2 aperiodic loops which look toward Europe. They are 100 feet or so apart. Works well, and I use this setup as follows.

Rick, my application is for an in-band RX antenna, but on a higher band. I just thought the guys here might know more about the NCC-2, MFJ or QRM eliminator than most others. One thought was to create a 2 ele phased vertical array for the RX antenna with a known pattern and put the null

What's your application Kenny and what would you be feeding the antenna output of the phaser into? Rick Kunath, K9AO _ Searchable Archives: http://www.contesting.com/_topband - Topband Reflector

I am not sure "predictable" is one of the attributes I would use when using one of these devices. Really - the real benefit of them is to annihilate a local noise source. I remember getting a really deep null (50 db) on a station that was about 1 mile away with a similar device. I did spend
