Main difference in setting up a C band and KU band satellites dishes?

Sorry for not being more informative, and much clear on my statement. When I mentioned the dish motor I was talking about the GEASATpro GS120 motor being installed on the 1M Winegard dish not on a 1.2M dish. The dish does jerk some when traveling the arc, and noticed that it at times struggles to move off of the center of the arc.

I do have a 1.2M "Commercial" dish which I was lucky to have scored it from an old gas station. This dish is made out of fiberglass and it is very heavy for it's size (approximate 35#). I would also like to have this motorized. Did some reseach on the dish and it suppose to be an "Andrews" dish, which in reality has changed names three times. Anyhow the dish right now is installed on a NPRM at ground level, and pointed to 97W Galaxy 19. To me it is a waste of a dish by not being motorized.

Back to my original question, what would be a recommended good motor for the 1M Winegard dish, and if anyone knows of a good working horse of a dish motor for the 1.2 "Commercial" dish please point me to the right way. LOL!!.

As always Thanks.

Maybe this will help a little. I have two 1 meter Winegard dishes and am using the large STAB motors HH-120 for both and have attached the directions to this post. The english text is woven into the instructions. They are very detailed and well thought out and are the best directions I have come across over the years. They go through the same press down on the dish that you were asking about! The motors are excellent if you can find them, but the directions apply to all similar motors and dishes. Watch the dimensions of the motor output shaft and the Winegard collar size. I had to use a piece of split 2 inch ID pvc tubing to get a good tight fit between the motor and dish. I believe you said your lnbf were PLL types. It is best to align your dish with a standard LNB, then put the PLL on and touch up the LNB alignment, not the dish alignment. The PLL lnbf can pull a signal a lot further from the center of the satellite than a standard lnbf. Good Luck!
 
A Stab HH120 would be the only Ku motor that is rated to handle the weight of a commercial 1.2 meter dish.

IMO, PLL lnbs are highly over rated for television fta.
Dishnet and Direct Tv would have PLL lnbs on all of their dishes if they performed at a fraction of the level that the sales people have claimed.
Marketing ploys come up about every two years for lnbs. Not long ago, we were told that .3NF lnbs were better than our .6 or .8 NF lnbs. Later this number was dropped to .1 NF. All of this was total BS in the real world but they have to do something to make people buy something.
PLL lnbs are designed to work on narrow signals such as data. PLL lnbs will have little if any real gain over the DRO lnbs we use now. PLL lnbs have been around for years. If they were as good as the sales people advertise to be then all of the providers would use them! EB
 
Just finished weighting the 1.2M dish, and with the two side bars, the LNBf arm (bar) and the LNBF, the dish is pushing 38+ Lbs of dead weght.
Went to Sadou's site and they do not have anymore Stab HH120 motors on stock, but they are offering a DG380 motor which is rated to hold a dish weighing up to 31 lbs.

Did find one Stab HH120 motor on Ebay, the dealer is from Canada but does not stipulates the load capacity of the motor. Will continue searching the internet.

Your 1.2 meter dish is not designed to be motorized. The Satb HH120 will be the only Ku motor that I know of with a pound rating that is close to what your dish weighs. Most Ku motors do not include a pound rating for a reason.
There is a fixed amount of energy that can be had from the output of a fta receiver. An actuator and positioner would better suit your commercial dish than any ku motor. EB
