Wouldn't it be easier to just use a single
higher gain yagi? I'm not sure of the gain of
a "moxon" antenna, but seems they were a
compromise reduced size, or wire X design???
Not sure...I'd have to look into moxon antennas..
I use just a single 3 el NBS yagi and get
about 9.4 dbi gain or so. "free space" MK
