I do not recommend a antenna amplifier , the Tv transmissions are strong and should be received on all 4 Tv's down to at least WDCI-LD channel 30 Daystar.
Because WOCK-CD channel 4 ,
http://www.americaone.com , is transmitting on channel 4 .
Install the HD7000R All channel antenna.
All channels are , VHF low band channels 2 thru 6 , VHF high band channels 7 thru 13 , UHF channels 14 thru 69.
