re: Multiple feed antennas around a tower:
This type of antenna was written up in Ham Radio
Magazine (rip) some years back. I just thumbed
past it the other day.
The math and the information to cover around a
large tower with a quasi omni pattern using
directional antennas was shown.
If I see it again, I'll scan it and send it
in. I sure miss Ham Radio Magazine...
