Does the NCC-2 create a predictable antenna pattern? Im just wondering how to null the noise but not create some weird pattern which may also produce a null in the desired direction. Regards , Kenny

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

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 - Topban

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 creat

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 160, a bit on 80. My Bevera

If you are going to use the NCC-2 to null a nearby in-band transmitter, I think it's very likely that the NCC-2 will get overloaded by the extremely strong RF and not be usable. I've tried this befor

Thanks for all the comments, but knowing what the resulting antenna pattern seems elusive. I need in-band RX antenna for a mult station. Typically antenna separation, front-to-back and polarization a

I think the concern about overload is another reason to not consider it. That box is not designed to handle a strong signal like another transmitter. One other solution is to try and come up with a c

HI Tree, Thanks for your input. I'm leaning towards a 2 element phased vertical array with a quasi-cardioid pattern for my application. it will avoid any phasing box overload issues. 73, Kenny K2KW _

OK Kenny. I understand now. Not all of the TX will be under control of the transceiver at the operating position that is using the in-band antenna, so you need RF protection while also receiving in-b
