I decided to jump on the bandwagon and picked up a orby dvr today. Planning to get a 30 or 36in dish soon but being the inpatient person that I am I went out and found two Primestar dishes. First one was laying one the ground still on the pole ready to load up but unfortunately the bottom of the dish’s was busted for the lnb arm so picked up another one that was froze to the ground that’s in perfect shape once I cleaned it up. Since I have 2 lnb to pick from I was wondering which one I should go with. Also how do I change the screw setting on it?
