Eric, Could you please give us a little more information please. What radio are you presently using for your UHF repeater? Does it have a preamp and if so what type? How much power out of the repeater transmitter do you presently have?
Also what are you currently using for a duplexer and antenna feedline? The answer to these questions will help us determine if a move to a 100 watt PA is technically a sound move, or if other parts of the system will need to be upgraded as well to support the higher transmitter power level. While a lot of repeaters and links are made from Mitrek's including some of ours, I do not consider a Mitrek mobile PA to be continuous duty in any fashion, although at reduced power levels with added forced air cooling they perform very well.
