I realize that you state that you cannot go with any bigger antennas, but you might be able to fix this situation with the same size antennas if you go with a more focused beam. You state that you are running 24db panels. Panels generally have a pretty wide beam width. If you switch to a parabolic of similar size, you would probably gain at least 3db on each side of the link.

I can barley make out the tippy top of the grain leg that the antenna is on. On both sides of link I'm using 24db panels with R52's. Anyway the signal is not that hot, about -73/-74. TCP Throughput on normal 802.11a is 17.5mbps. Turn on Nstream and its around 23.5mbps. I can not go bigger antenna's or higher on either side of link. Believe me if I could I already would have. Was thinking about upgrading each side to an XR5. I'm thinking for another 6-7db improvement over what its at now. Does anyone have any experience with making a link like this work? I need 30mbps with Nstream and possibly switching to Turnbo mode and hoping for 60+mbps. Will amping each end with a pair of RFLINX amps overcome the attenuation and make the link more solid or will this cause problems? Kurt Fankhauser WAVELINC P.O.
