If 2 or more Tv's are connected to a antenna with a rotor this can be a source of conflict because the direction the antenna is pointed thats what every watches. . A 2 antenna set up works better because a remote control A/B antenna switch. A good way to identify a tv station we are working with is use the stations call letters. WGBA NBC , WTPX ION , WACY MyNetwork , are low of signal strength , please make a radar plot with exact address and the antenna height at 60 feet to see if can get the signal strengths of WGBA 12.5 NM(dB) , WTPX 5.3NM(dB) , WACY 1.9 NM(dB) up in to the teens or even the twenties this will get you reception. Right now we are exploring posibilities and not spending money.
