So a Quad, with a single boom (obviously) all interlaced, that can
operate on 20-15-10, but has seperate feedlines does not fit, but if it
had a remote coax switch it would? or would it not still since it still
has seperate coax feeds it;'s just that the switch is out of the shack.
Like a tri band quad that has 1/4 wave matching transformers for each
band, this does not fit?
Bummer?
