The issue is that the out of band emissions limits at the lower edge of 5.1 are (excessively) strict and as such the manufacturers have to either keep you from operating at the lower edge of the band, or reduce power as you approach the lower edge.

Subject: [AFMUG] 5.1GHz EIRP

Can someone tell me what a SM transmitting in the 5.1GHz band is allowed for EIRP?

I can’t seem to find a straight answer.
