C-Band Dish: Help Identify & Buttonhook Problem

[mmruzek]

Hi, I started in C-Band TV reception about 25 years ago with a used 10' dish. Now I am using the same dish for Hydrogen Line radio astronomy hobby at 1420 MHZ. My feedhorn is a modified coffee can. I was wondering 1st if anyone can identify the brand/make of dish from the photos? Also, the feedhorn mount is a buttonhook style that appears to be rusted-in-place. I tried WD-40, tapping it with a hammer, and a propane torch... no dice. Any suggestions for repair or replacement? Thanks! Michael

My guess is a Winegard.

Pull the lock bolt. Heat 'er up a bit. Feed it as much blaster as it will take. Tap it with a hammer. Tomorrow do it again. And again like Groundhog Day.
Or take it off the dish and fashion up a tub to put it in and look up "Rusty tank electrolysis" on the 'tube.

I have used PB Blaster with good results on old engines to free up the pistons. Should work on those stuck together tubes. Let it soak for a day or so. Then I would apply maximum torque to twist apart those tubes.

You might just switch your feed horn setup to quad legs, instead of the button hook... You can easily built them your self
