If you have a "batwing" antenna it's probably a Winegard. They offer an accessory element called "Wingman" that attaches without tools and makes a huge difference. The original analog TV channels 2-13 were VHF, then UHF was added to provide analog channels 14 and up.
DTV/HDTV broadcasting is ALL UHF! That's where Wingman comes in, because the original Winegard batwing was built for VHF. Adding it to an older antenna optimizes it for UNF.
So even if your favorite channels are 4, 7 and 11, and they come up that way on your channel display and remote control, they are really UHF channels. Computer wizardry allows them to display with legacy channel numbers.
Bottom line, your Winegard will drive an analog TV using a converter box, or a new digital TV straight from the antenna (through the booster of course!). But adding Wingman will help.
