I also meant to add, it was very noticeable when I was operating as VP2EAG from Anguilla, both with the Arrow and HT on UO-14 (sobsob) and with the dish on AO-40 S-band. The first pass on AO-40 was from a hill on the island, with the 18" DSS dish upside down on the windshield/hood to get down to the 6 degree elevation the sat was to the west. I noticed a big signal bump approaching the horizon, and a bit past my predicted LOS, even on 2.4 GHz. Great memories of that, and working from neighboring islands on AO-27 and UO-14, and running dozens of EU stations at 3AM on U/S, even split, spreading them out over 20-30 kHz.
