Mine came from Radio Shack so hard to tell who made it. I'll probably go up to Universal Radio for my replacement. I need to get a coat of paint on my tower and upgrade the antennas and amp. for HD. Also my rotor has frozen up. Figured while I'm up there might as well get them all fixed up for another 20 years.
I was hoping to get rid of the VHF antenna and go UHF only but one station out of the nine locals stayed in the VHF band for their new HD channel. So I'll have to go with a combination or dual antennas again.
