Ok… I did not know that I should probably read up on UNII/OOBE
Thanks for that explanation… From: Af [mailto:[email protected]] On Behalf Of Mathew Howard Sent: Monday, October 12, 2015 6:22 PM To: af Subject: Re: [AFMUG] AirFiber Link Calc If we were hitting the EIRP limits, that would be true. but it isn't the EIRP limits that we're hitting, they're limited by the out of band emmisions. The EIRP limit in UNII-1 is technically 53dBm, but because of the OOBE limits, no radios that I'm aware of can actually hit that - they all have to keep the TX power below 21db or so to stay within the limits.

It's because of how the new out of band emmisions rules work.

You should be able to get to 49 or 50 with it set to 30dbi. if it's set to 23dbi (the minimum/default, I think) it will limit you to 44... but that isn't going to change the actual output, since 21dbm conducted TX power is as high as they'll go in UNII-1.

Mine maxes out at 44 on 5225… From: Af [mailto:[email protected]<mailto:[email protected]>] On Behalf Of Mathew Howard Sent: Monday, October 12, 2015 4:16 PM To: af Subject: Re: [AFMUG] AirFiber Link Calc Expect better than this... Distance is a bit further, but this is a 2' Rocket dish at one end and a 25dbi Force110 dish at the other. You're going to be limited to 49db EIRP at 5225. [cid:[email protected]] .
