The Decibel DB-4076 series is rated for 250 watts. This is the model that came from the factory in my Mastr II 100 watt UHF repeater. They made it in 2 versions, 3 cans and 4 cans, the 5 MHz split units using 2 TX and one RX, and the 3 MHz split units using 2 and 2. I find good

Guys, I think it's time to get back to basics. The question posed is: How much power should you run through a 350 w duplexer? The simple answer is: Not more than 350 watts! Many of the responses asked about how much power do you need to run, but that is not the issue. We don't need to

Personally, I'd go up to 300 watts which would give you a 10dB improvement. That much WILL be noticeable. Also you won't be pushing everything to the maximum it's capable of. Gives you a bit of a safety margin. But then again, the FCC rules state something about [...the minimum power necessary

Mel, Depends mostly on what duplexer you have. Many base type duplexer's will handle 350 W, but at that level of TX power the duplexer might not do enough for the receiver and cause desense. When running only 4 cavities this often happens even with 100 W better commercial rigs. Running
