First get that SWR as low as possible. 1.1 to 1.3 max. Next get a good tech to tun down the output on the radio to about 2 watts. It won't put out much bare foot but if your running the amp you're good to go. If you keep running 4-5 wats into that amp you could lose your finals.
Good SWR, tuned radio for amp and a good antenna and you'll be smokin.
