If you have 10 dB/km rain, 2 dBi doesn't get you very much.

However, if you want the higher QAM rate, half the distance to start with and go from there. That assumes both boards are exactly the same.

Does anyone have any experience of how much better HD is?

But UBNT say AF24 = 13 km and AF24HD = 20 km. So I assumed it had more EIRP and therefore some more range? Just wondered if it would be a 50% increase in distance in the real world.

AF24 works here well up to 3 miles. We have one at 4.3 miles, which to date has worked well but as we have had no rain to speak of for years it’s hard to know what it will do in the rain. Anyone a feel for the % better a 24HD is over 24?
