What size cavity did you say you were using?



It's about 3' long, 8" diam. Don't have any model number on it. I bought
8 at a hamfest for $15 each because it won't work on the 2 meter ham band.
Works great from Ch 10-Ch 72, about as far afield as we get....

Your cavities must be new to have such wonderful specs...(c; You could
parallel those and offset the tuning on each to cover a wider bandwidth, I
suppose....Maybe parallel two, one for Ch 6-22A and one for 68-72? Two
humps in bandpass...
