Hey Old Guy,
What in the world are you talking about, if I may ask when you say, "they have a unit that just SNAPS into place on the antenna"? I'm definitely not the smartest when it comes to this TV stuff but, I've definitely not heard of anything that "Snaps" to the antenna that does any types of improvement. Thanks for any info.

I believe Old Guy is talking about the little snap on unit Winegard sells to boost the UHF sensitivity for their older TV Antennas, I just can not remember what they call it.
