Re: [Fixed] Not quite high enough to get LOS service from WISP

By the way... this has me thinking. What would it take to have a non-LOS link of two or three miles? Is that something that's easy/cheap to do, or are we talking thousands of dollars?

You won't see that kind of throughput on NLOS. And LOS is more than just seeing the tower when you're dealing with that type of speed. You need 100% clear Fresnel1 and probably >60% of F2 if you actually want to get to 20Mbps. Ironcially NLOS needs more ground clearance than LOS does to be stable because Fresnel Edge Refraction can be much more severe at the lower frequencies that NLOS needs.
