I only have one tower up at present and it serves for hf and I have a yagi on top....so....the repeater antenna is on a mast above the yagi.... Back 25 years ago, I could climb without too much trouble....now that I have gotten into my "golden" years, I don't climb so well..... Guess the time has come to get some young buck to put me up another tower and dedicate it to the repeater system.....

If so, you can take, say, an 8-bay UHF and mount a 4-bay VHF at 90 deg from the UHF elements on the same mast (or a 2-bay VHF on a UHF 4-bay). There's a number of ways to do it and still come out with a more-or-less omni pattern. If you need one feedline, TX/RX and a few others do make commercial grade cross band couplers. Put one at the antenna and one at the repeaters. ------------------------------------------------------------------------------ No virus found in this incoming message.
