Hey thanks for your response. The main one is an RCA 65 mile range outdoor antenna I purchased from Lowes. The second one (which isn't hooked up; only the first one) is a 40 mile range RCA from Lowes. I am wanting to receive both Columbia, SC and Augusta, GA tv signals. Right now, my antenna is pointed towards Beech Island, SC where the transmitters are for the Augusta stations. I live almost 60 miles from the transmitters there. (In Pelion, S.C.) I can receive all the Augusta stations except for WFXG Fox 54, which I've heard is hard for most people within the 30 mile contour to receive. I live probaly 50 miles from the transmitters in Columbia. Anyway, was wondering if this is a good or bad idea; and if 2 outdoor antennas facing opposite directions would cause the signals to "cancel" each other out.
