I googled , K18CD 18 , KWAZ-LP 35 , K27GX 26 and these stations are said to be not transmitting. . KFLX-TV 51 is said to be transmitting as a FOX affiliate. You have FOX KPTM-DT UHF 43 at 45 degree magnetic compass. I also recommend a Winegard HD7696P antenna with a HDP-269 preamp. point the antenna at about 37 degree magnetic compass. Here is how to point Tv antennas ,
