Re: Scavenging parts





  Zooming in it looks like your dish also has a Cuttler Feed
Note the 90 deg twist in the feed.   For years I wondered
"Didn't they know what polarization they wanted before they
 did the design?"
There is a surface current that runs back down the outside of
the WG. Goes into the dish, and gets radiated.  SIDELOBES!
The 90 deg twist makes the signals at the feed cross polarized
 to the sideblobes.    Someone did know what they were doing.
