It’s easy enough to run the numbers. 5 GHz FSL at 1 mile is about 112 dB. Let’s say the combined gain of the 2 ft dishes plus coax loss is about 56 dB. So if I’m doing that right, it’s a net loss of 56 dB. (I’m not 100% sure the antenna gain in dBi is the right number to use.)
FSL at 300 feet is still 87 dB, but it would work with 10 ft dishes.

Im curious what the real world loss would be if we used them on a midpoint with the feedhorns patched together. Like for a business buried in trees that has an old tall barn with no power but line of site to our PoP. this is a really common occurrence. All we would need to do is get the feedhorns replaced with dual pol horns. This is on my list of things I would like to set up here shooting around the corner of our building out of curiosity, but I never have time to play with it -- If you only see yourself as part of the team but you don't see your team as part of yourself you have already failed as part of the team.
