Re: [AFMUG] 11,6ghz same antenna
Years ago. The problem is that I could not get the pattern legal for the smaller antennas I built. I never built 6’ or larger dishes so legally 6 GHz was out for me.

I wonder what the ballast weight would be on that bad mother grabber on an npm.

Takes more than diplexors or filters. The feed of the reflector is a bit tricky.

man that would be bad-ass to run two ip20c-hp's or NxIP20c's in both 11 and 6 on the same dish!
