You were told correct, Charlie made a ton of those back in the 90's and I've owned and operated over a dozen. On all of the apps I filed, I used a gain of .047 for the 1 bay and 0.99 for a 2-bay, but as far as an official spec sheet I"m not sure they exist.  Not heard from Charlie in years, was in his shop in Dallas at least a time or two along the way as well.. wow, that brings back memories.

We were told previously that it's likely an "MSW" antenna, made by Charles Shoemake of Texas.  Does anybody have a lead on finding a spec sheet for such an old rare model?

Thank you!

We are trying to locate the antenna efficiency for an antenna at one of our translator sites.  Here is a link to the picture: https://drive.google.com/file/ d/0BwdIg6tT9Bk9eHF5aHByZlFiM2s /view

Please ignore the line running through the antenna.  We are just trying to assess the efficiency of the antenna.

Any suggestions or help would be greatly appreciated.
