Install a Winegard HD7000R antenna aimed at about 240 degree magnetic compass. The HD7000R is a all channel antenna that will receive , VHF low band channels 2 thru 6 , VHF high band channels 7 thru 13 and UHF channels 14 thru 69. Here is how to aim antennas ,

The HD7000R does do a fair job of reducing multipath ( reflected signals off of , buildings , hills , mountains , trees and etc. ) because multipath is usually weaker then main signal and is out of timing phase ( arrival time ) at the receiving antenna.
