<---One of my UHF repeater antennas is up a 167' tower, with hardline running up there. I also have a 2 meter antenna for my remote base up the tower too. The same hardline is used for both bands and it works just fine. Although it is kinda strange watching the wattmeter go from 70 watts with just the repeater talking, to over 100 when the remote transmits :-) Just get one that can handle the combined power, since both repeaters will transmit at the same time. I think I used a pair of Comets for my installation, rated at 250. I figured that was conservative enough and so far, no problems. Truth be told, I doubt there is much difference between the different brands anyway. A couple of low-Q bandpass filters ain't exactly rocket science :-) Ken ------------------------------------------------------------------------------ President and CTO - Arcom Communications Makers of state-of-the-art repeater controllers and accessories. http://www.ah6le.net/arcom/index.html Be sure to see our products at this year's Dayton Hamvention!
