Wouldn't that minimize the db loss ??? than using an antenna combiner???

Alan909,

According to Antennacraft, what you describe is a:

"Built-in VHF feed thru feature allows you to add an MXU antenna to an existing VHF antenna."

http://www.antennacraft.net/Antennas/AntennasUHF.html

In other words, allows you at add a VHF antenna to your antenna. Probably it is designed to block UHF signals that may be picked up via a VHF antenna.

This is (was) a common design practice, since UHF signals from VHF antennas tend to distort the beam pattern of the UHF antennas.

If so, the connection would not be good for stacking two UHF antennas.
