Get him to send you pictures of:
- these dishes with a yardstick laying across 'em -
- the back side of these dishes, showing the rear to be molded or stamped
- the mount, which may show some heavy duty hardware, elevation screws, etc.
- whatever Primestar dishes he has, with yardstick, front/back, etc.
Ya didn't say if he wanted money or just wanted to find 'em a new home.
If they are as advertized, and the Primestars are ROUND, or 84e elliptical,
and you can use them... then $10 each wouldn't be bad.
Of course, a 1.2 meter (4') Primestar round, would be a supreme find. -
I've got a DirecWay elliptical, and some smaller Hughes ellipticals, and while useful for experiments, they're not quite prime beef.
Of course here, with no rain, I am happier with smaller dishes, than someone in a more rainy area.
So, use your best judgment. - :up
