Rf level is rf level. TX power + antenna gain - path loss + antenna gain.... I think Adam makes a good point. If both systems were making legal eirp on the same path, the signals should be the same. Unless I'm inexperienced too? Maybe this telrad stuff is just too complicated for us silly wisps. Kinda funny the attitude put forth so far by telrad and their main distributer it's like their poop don't stink and we should be kissing the ground that they are even considering selling it to us ?
