Yeah, no. 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.

Can you please share the ref where and when this was changed ?
Thanks.

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.

what rain zone are you in?
yes our link is in 18GHz
honestly if you need 1gbps with 4.5 nines with 2' dishes at 6
miles you probably need to look at 11GHz or 6GHz instead of 18GHz.

Cambium 820's will be down to around 400 meg at 4.5 nines.
We want the link to hold 1 Gig at 4.5 nines.

What does link planner say you need?
Five nines I presume?
