While researching the old A/S Superscanner antenna, I recently ran across a site that has a list of some of the antennas that Antenna Specialists once made. I found one called the Match Maker that I had never heard of or seen.
I'm curious if anyone of you out there has.
The link is here: http://www.cbtricks.com/ant_manuals/ant_specialists/mr_77/index.htm
It's a wild one that's for sure.

Neat looking antenna! I don't think I've ever seen one! I've been around since the 70's too.

The MR-77 begat the "Jo Gunn" and "Gizmotchy" beams.
In vertical polarization mode, the work the same as a regular beam with the same number of elements (think ground plane 1/4 wave, if you will). In horizontal mode, it acts like a horizontal yagi with end loaded elements.
Don't get too excited...

I have never seen one in person and was just curious about them.
I still miss my old Superscanner. i know some folks didn't like them, but mine worked quite well for me at the time.

The Super Scanner did work well, as long as you got it way up in the air.
A lot of CBers that stuck to the rules had mixed feelings about the mounting height of a Super Scanner. Those of us who were around back in the licensed days remember the rule about antennas and height above ground or mounting structure well. The rule is still technically in effect, but appears to no longer be enforced as vigorously as it used to be.
The rule said (simplified) that an omnidirectional antenna could be either 60 feet above ground, or 20 feet above the mounting structure (like a building). A directional antenna (like a Yagi) could only be 20 feet above structure OR ground.
So, if you followed the rules to the letter, and you ran your Super Scanner in omni mode, you could have it 60 feet above ground (and they worked very well at that elevation). However, if you ran your Super Scanner in directional mode, then you couldn't have it more than 20 feet above ground. It got VERY confusing.
I remember some very heated on-air arguments about that. However, I am unaware of any FCC enforcement action against a Super Scanner owner for being too high above ground.
The major advantage to the MR-77 beams was you could stick to the 20 feet above ground requirement without the elements dragging on the ground or your roof.
What the FCC never clarified about the directional antenna rule was whether 20 feet meant to the highest point, or the boom. Most people, including manufacturers, went with the boom height above ground. Lots of those 10 foot "roof towers" were sold to people with beams.
