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 are the main tools for that. When I run out of
room
I was wondering if phasing from an NCC-2 box is another tool to consider. But I
don’t want to consider it without knowing what the resulting pattern would be.
Many thanks, Kenny K2KW
