Sounds like another field test coming up. Could be fun. FYI, the 18" dish used by Direct TV and Echostar calculates to have about 18.5 db gain a 55% efficiency @ 2.4ghz. If your really good with physically matching the feed to the dish, you might get 19 db gain at 60%eff. Let me know how you do in the "tests". Warm Regards, And Happy New Year, Ray, W4BYG
