Thanks.
I remember the 3 foot ruling. Never heard of a 2 foot rule, and yes I had forgotten the minimum distance requirement. It seems the 5Km rule is being ignored, I am sure people are reporting short links with AF11…..

The minimum diameter in the L6 band is 3-foot and >/=70dB F/B ratio. I believe only a few Radiowaves and Andrew/CommScope high-performance dishes meet that spec. I believe that was part of the same change that allowed 60MHz channel bandwidth. The upper 6GHz band is still limited to 30MHz channels and 6-foot or larger antennas. Also, the minimum path length for both lower and upper 6GHz bands is 17km. 11GHz is 5km. I believe there are special considerations and waivers to this for things like public safety agencies and such. On 4/19/2018 4:27 PM, Faisal Imtiaz wrote: >>>Fcc changed the rules.

You can do 2’ in 6ghz now. Why are you limited to 2’ dishes?? Can you do a 2’ and 3’ (or 4’)?? What you are trying to do breaks the laws of physics no matter who’s equipment you use.
