Performance Chart:
Chuck –
I used the BPF up at a SOTA site with a significant cell/microwave/comms site and it did great. I had a contact with a guy about 15 miles away and his signal was very strong, full-quieting and S+20 or more. Also I pushed it a bit more than 10 watts and didn’t seem to fry it.
