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
conservative at 100
watts to the antenna and see how it goes. Thanks to all.

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.

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.

commercial rigs. Running
