Whats the spacing? There’s a different gain factor between 1/2 wave and full wave spacing of the bays

It's actually a 2 bay.  I sent the close up picture and should have included links for both.

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.
