A:Answer You will need more than Antenna paired together to get all your local over-the-air HD TV signals.
Get 2 AC-powered TV Antennas, and then use a Coax Cable splitter, and then pair them up together.
Despite the incompetent advice from some Best Buy salespeople, this DOES indeed work very well, and WILL increase your TV signals from where ever they come from in your area.
I didn't listen to them, and bought a second Antenna, and paired it with another powered TV antenna, and it brought in hard-to-reach over the air TV stations.
Problem solved.
