I recently switched to an antenna as a cost cutting move and Sling TV and I realized WFAA has come in MUCH clearer in northern Tarrant county (Keller) then even two years ago, but why are WFAA 8.1 and WFAA 8.8 both in 720P? Is this normal? Also, anyone know what is coming on one of the KFWD subchannels?
