Yep, pretty sure that's a Paraclipse. There were some knockoffs made, but I don't think any of them had that feed cover. The polar mount was standard, mine has the H to H mount. Doesn't really matter, unless you have clear eastern sky...LOL..
Now, should you get it. Well, its a 12, so that will help. They are very rugged, designed originally for hurricane areas, I have some old STV magazines with paraclipse ads in them, they show islands in the Caribbean with various dishes after a storm, all of them in the ad were destroyed but the Para not only survived but still tracked the arc. Now that was the 1980's I bet they weren't checking Ku, much less S2...LOL..
But yeah, its worth it. my thread has all kinds on info in it, I took mine in two when I got it for transport, wasn't bad at all to do.
Feel free to PM me if ya need anything, I will do my best to answer ASAP.
