The arangement of the transmitters and the weak and strong signals makes this a tough one. Uhf 28 is right there with a very strong signal so I am hesitant to use a preamp for the 303 stations. This is a 2 antenna soluition. . A high gain antenna is need in any event for the 303 stations so the Winegard HD8200U is directed at 303 , no preamp or distribution amp for now , connect both Tv's. . And a Winegard HD4400 pointed in the direction of channels 19 , 36 , 38. . Separate runs of coax from both antennas and separate 2 way splitters with remote control A/B switches at both tv's. Radio Shack has the remote control A/B switch.
