Only one site have I seen big coax up the tower. Tsunami gear worked well on a 150' LMR400 but they had like 3 megs...
We tried putting the Radwinmux (Ceragon?) ODU at the base of the tower and it was comparable but caused lock ups and loss of link a few times. Once that was put by the antenna problems went away and throughput improved. In my little experience long coax runs has not been good when it's carrying 5GHz. Redline AN50s using rg11 do better (not sure what it carries).
