See this is the part I have an issue with with the rules. It states I can use higher power for a point to point link but doesn’t state what kind of antenna I have to use. I could literally use a sector on both sides of the link and it would be point-to-point.
Give me that makes the rules pointless. > On Jul 6, 2020, at 8:51 AM, Mark Radabaugh <m...@amplex.net> wrote: > > This was something WISPA fought hard for due to the huge impact it would > have had on full power operation in UNI-III.
