The 'pending applications included' for digital stations shows that , WWAZ is transmitting on digital channel 5 and WMLW is transmitting on digital channel 13. The C2 antenna is a UHF antenna and will not receive WWAZ. And may or may not receive WMLW. For a outside roof top antenna , I recommend a Winegard HD7000R. Aim the HD7000R antenna at about 80 degree magnetic compass. Here is how to aim antennas ,
