There is no GE MASTR II (88-split indicates that you're looking specifically for a GE product) that does 200W at UHF. The MASTR II Station/Repeater PA (solid-state as you requested) maxes out at 100W. In the Station/Repeater form, it's rated for 100% duty-cycle (depending on altitude and ambient temperature) at that power level, which is usually *plenty* for a good repeater. Most of us run them de-rated to about 80W or so, in practice. Minus duplexer, isolator, and maybe (hopefully not) feedline losses, the power that reaches the antenna is often quite a bit less. You could run a lower power MASTR II solid-state PA into a modern 200W PA, but I doubt the few more dB from 100W to 200W is really going to produce a balanced repeater for 5W hand-held users or even 50W mobile users, unless you're planning on building multiple receiver sites and/ or REALLY work hard on *maximum* performance of your receive system. Typically the only time the use of higher power PA's is required is in that type of application. It often requires a very expensive duplexer capable of handling the higher power and also that provides enough isolation between transmitter and receiver frequencies at the higher power levels. I haven't seen the usual "reminder" on the list lately, and they're too modest to remind folks: Don't forget that the guys that host the Repeater-Builder list, Repeater Builder, Inc. "the company" do a nice job on MASTR II repeaters and they have parts in stock. Have you talked to them about your needs?
