Yea, your two little dishes are the regular Dish 500.
The big dual LNBF could still be any of three models.
As I recall, they are identified my molded-in text or a sticker on the front, and how many connectors they have on the back.
Possible answers are: none, dishPro, dishPro Plus, 2, 3, 4.
Not sure knowing the answer is useful, as their barker channel is useless.
We do have a minority of members who've logged hot transponders on some birds.
I even whipped up a DirecTV Phase III dish with an Invacom several years ago.
But that was for the particularly easy Whitesprings.

Dish 500's are harder to use because the LNB arm is short to accommodate their plastic 2-LNB holder.
Bigger dishes from DishNet and DirecTV, say 30" wide, are better candates and a lot less frustrating.
Your Primestar looks like a single LNB and feedhorn for one of their elliptical dishes.
The arm length varies to match each particular model.
Without the correct dish, it's just a wall decoration.

Dont throw it away; someone might use the feedhorn or that old LNB. (we call 'em Dove Bars)
