John, I agree 65 watts on UHF is good. My VHF repeater runs 15 watts out of the duplexer and I get great coverage. Of course an good antenna at 1175 ft HAAT with 1-5/8" feedline is the secret to its success, hi.
Sounds as if you are using the Comet or other "duplexer" (don't know why they call it that for it a crossband coupler) for marrying the two bands together. Don't believe Comet on their power handling specs. They often talk PEP. I've had number of problems trying to marry even 50 W per port with them. There are commerical VHF/UHF crossband couplers, cost more, that can easily handle 100+ Ws per port continously. One is the EMR DB DB4337 100 W at Tesco is $221. Telewave TS1545 400 W $222., EMR's 6052/CGK-E at 125 W for $331. I think the power rating is total power from all ports. Using crossband coupliers can be great way to get VHF site for few commerical people use VHF, but have good UHF systems. If one knows someone they could get good feed line having only to supply the couplers and antenna. This is how I got my 1175 ft site. ron > ------ Original Message ------ > Received: Mon, 14 Nov 2005 12:51:07 PM CST > From: "n2len" > To: [email protected] > Subject: [Repeater-Builder] Re: Diplexer for UHF/VHF Repeating... > > > I appreciate all the input...Right now, Out of the duplexers. 65 > > watts UHF and 25 watts VHF.
