Untenna
Sorry to hear about the apparent demise of Com-Rad.
I knew the founder, Jim Waldron, many years ago. He and his wife were both very charming and personable when I went to visit them to inquire about a 2 meter version of the antenna (the Untenna started out life as an amateur radio product). Jim, as I recall, was a fairly accomplished piano player as well as an antenna expert.
The VHF version of the Untenna worked very well, and several school bus companies in Western New York used the low band version as well.
Funny, I hadn't thought about those antennas in years.
