Bryan/Ryan: Are you guys doing the link between the two HamWAN sites via RF? If so, what is the link budget? Since you tested it in the winter, I suspect lots of Fresnel zone issues and reflection off of the bay plus tropo issues in the summer. How do I know this? I had a 2 watt/30dBi gain Horizontal pol 7GHz hop from across the street from RayJay to Riverview over Hillsborough Bay and in the summer, the path was a mess due to temperature inversion layer differences over ground vs the bay. Needed diversity receive antennas at Riverview. I had a hell of a time with that path! Thank god for Fiber - The RF path was the secondary STL for WFTS. The path over the bay is BRUTAL in the summer, especially in the early morning/late evening. Wonder how this will affect that link. It will be interesting to see. Don't know how much fade margin you guys have in the link budget. Any thoughts? -lu-W4LT
