Thansk for the input. That is almost exactly what I'm going to put on the air as far as cans go. I'll have a Hamtronics exciter and receiver amped up by a 110 Watt Micor base amplifier. Just about the same heights too. Antennas are both staion masters. but I like knowing that what I have been thinking about will actually work.
One other question someone may know. Is it possible to run say a VHF and a UHF repeater off a dual band antenna with a diplexer or is there going to be issues.
