RTN Retro Tv Network KWCE-LP UHF-27 is a analog transmitter. MyNetwork K47DW UHF-47 is shown both as a analog and digital transmitter. TBN Trinity Broadcasting Network K45IY UHF 45 is a analog transmitter. Unknown programing KBAC UHF 41 is a digital transmitter. I recommend a 2 antenna solution , 2 Winegard HD7695P antennas. And a Radio Shack remote control A/B coax switch box.

Point one antenna at magnetic compass 28 and the other antenna at 127 magnetic compass. The 2 antenna solution is the easiest to operate. Read and understand this
