At the advice of many here on this reflector, I have changed my bn-86
to the bn-4000 as well. I didn't want a failure in the middle of a
snow storm at 100 ft in the air. But before I changed it, I also
pumped 1500 watts a few times in it with LOW SWR. Many emails told
me that a high swr at high power would fry it. Good luck....Steve
