Re: Primestar dish from the trash

Yeah, I haven't done this test either.  The brackets seem "beefy" enough to 
add lots of weight.

Yep, I've done this too (after being given a nice description by Jim K6CCC).

Boy, I don't think I'd put the Primestar dish on my G-5500.  Seems to heavy 
and not a very good center of gravity, but again--like you I haven't taken 
the heavy brackets off.

Well, I bet it's close.  Perhaps the Primestar could be 3 dB better since 
you can use a helix feed for circular polarization.  I hope to experiment 
with this soon, but not sure I can put any real numbers on things.

>Even if I can't rotor-mount it, It was still too cool a thing to pass up.

Yep, I got mine for free, too.  It's fun to play with, and to me, that's 
most of the fun of satellite radio!
