Rick, my application is for an in-band RX antenna, but on a higher band.
As detailed in the link I posted, the NCC2 is designed for use on the
lower bands, 160, 80, maybe 60 and 40. My measurements show this. I've
mostly used the VE3DO array on 16
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
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 toward

Here's how it can be made to work with suitable antennas.

What's your application Kenny and what would you be feeding the antenna
output of the phaser into?

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 some
