Any suggestions on how.to improve antenna reception?

If you are too far from the actual TV transmitting towers, you may not have a good enough signal. The best bet is an outdoor antenna that is high, with an amplifier..(pointed in the direction of the TV towers. Most cities have the towers in the same general area.) With digital signals, there is no 'weak' reception. It either will be there or not. Most indoor antennas do not work well.!! Off the air signals do not come from a 'satellite'.. They are from large towers at the transmitting site.
