One of the problems is that those frequencies are not grouped in the same ranges, they are distributed over several 'bands'. This involves a 'government' agency so keeping it 'simple' is a very good idea! I honestly think a 'fan' dipole system would probably be the best bet, maybe. A matching device at the roof level, or the feed point of 'one' antenna is certainly a possibility, but that complicates that 'simple' thingy. This isn't for super long distance communications, more than VHF/UHF though. So, I don't think it's going to be all that big'a problem, just different from what's commonly been done by the people involved in it.
Another one of the 'problems' is getting around some of the commonly believed 'myths' you find with antennas, ooooo that's fun all by it's self! I think that's one of the good things that happened the other day... 'miracle antennas', etc.

[QUOTE="W5LZ, post: 266392, member: 129"] One of the problems is that those frequencies are not grouped in the same ranges, they are distributed over several 'bands'. This involves a 'government' agency so keeping it 'simple' is a very good idea! I honestly think a 'fan' dipole system would probably be the best bet, maybe. A matching device at the roof level, or the feed point of 'one' antenna is certainly a possibility, but that complicates that 'simple' thingy. This isn't for super long distance communications, more than VHF/UHF though. So, I don't think it's going to be all that big'a problem, just different from what's commonly been done by the people involved in it. Another one of the 'problems' is getting around some of the commonly believed 'myths' you find with antennas, ooooo that's fun all by it's self! I think that's one of the good things that happened the other day... 'miracle antennas', etc. :) - 'Doc [/QUOTE]
