WAFB has been fine once I added the VHF antenna. It was only a problem when I had only had the CM4228. Just always kinda rubs me wrong when I put a CM4228 at buddy's house and his picks up KPLC(RF 8) just fine and I'm closer to WAFB than he is to KPLC. And this was before KPLC upgraded their power. WAFB has always been a thorn in my side for any OTA installs I've done for people.
And the fix for WVLA at my house was raising the antenna about a foot and shifting more towards Lafayette. I was able to find a happy medium and I now get WVLA at 90%. WGMB still knocks the doors down at 100% so I'm good now.
