Antenna is EVERYTHING. I looked through all the specs and have been using the Wineguard HD7010. Its about $45 and has about 4 to 8 gain from channel 3 to 69. If you use this antenna and RG6 you will get all those channels 24/7 and more you didnt know were there. This is assuming all the transmitters are in the same general direction.
The best part is its made in USA
