2 omnis on one tower, same height

Would there be any problems with having two Omnis on one tower? 906 and 915 MHz, Horizontal polarity, one each side of the tower at about 100 feet. Horizontal separation would be 12 to 20 feet max. Both would be synced. Would they over power each other? Would I need to have vertical separation as well?

I can not get to the top of the tower so 2 Omnis will give me better all around coverage.

If only those 180 degree sectors were available!!!



3 120’s?

Actually, the 120 degree sectorized antenna’s act like 180 degree antennas… We have a site where we have 1 facing north, and the other south, and we are able to connect just about anywhere around the site.
