I was just wondering how the SBGH GH10 curved reflector worked out, 300ohm. I've been going for some deep fringe channels all 2 edge or worse. I'm especially interested in channel 15 which I can get consistently with mild tropo but otherwise I get dropouts. I built a Mclapp with 11.5" whiskers and 11" spacing and it is marginally better that my 91xg. Since I have a heavy duty Rohn mount on the roof from a 4ft satellite install I may try a DBGH Curved reflector. Did you ever try that? Since the highest channel I cannot get reliably is at 41 (comes in most of the time especially at night) and the ones that come in intermittently are 36 and 20, perhaps the huge curtain antenna you modeled and balm tried to build would make more sense? Obviously the larger reflector for the SBGH GH would make more sense according to your gain charts. A little tropo last night and all the Buffalo stations came in solidly with the Mclapp. I have a Winegard yagi on a tower about 50 feet up that does fine with all the Erie stations to the north.
