Quote from: Jimboy;51517Been trying to find the specs on the antenna. Since it's discontinued all I could find is the install guide in Spanish on the Radio Shack site (vintage 1992). Any idea what the gain factor and front to back ratio is? Granted you now have interference but it all comes down to how well the antenna is capturing the signal in the direction you have it pointed and rejecting what's behind it.

There is a channel master near-equivalent.  I'll see what it is. Radio slack doesn't publish gain information.  I think the UHF yagi part of the antenna has between 11 and 13 elements, plus it is one of those corner reflector designs.  That should be a pretty good F-B ratio.

This is what antenna I am using:
http://support.radioshack.com/support_video/doc61/61157.pdf

13 elements UHF + bowtie element and corner reflector

The advertised distance for the antenna is
VU 160-XR VHF = 160 mi, UHF = 100 mi, Length = 140"

I know it's not gain, but that's all I could find.  Hard to tell which freq. this antenna was designed for.

Isn't that enough F-B ratio with the 14 elements?
