That's strange - some are getting it no trouble, others (like me) can't pull it in at all. My antenna could probably stand to be higher, as it does point towards some trees a ways away. But they are all naked now, so they shouldn't present a huge problem, and like I said, I get WHAS at 72-79 on my E86 (which is plenty good for a strong lock). But WDRB I get picks at 3-6, that's all. No amount of tweaking the antenna helped. It's on my back deck, about 20 feet up.
But since they are not transmitting EDTV I don't really care!
