let's get serious
Not to take away from all these good ideas, but . . .
Linuxman has a big flat roof to work on, that's five times bigger than my whole house!
If he wanted , he
could take his 27" TV up there! -

. . . and his Laz-E-Boy chair!
Plus, he's been through the alignment of motorized dishes to where he could do it in his sleep, and most probably does dream about 'em!
For his avatar, another one of our members shows a motorized Primestar bolted to the peak of his roof.
That guy's both crazy, and very experienced at installing and aligning dishes!
He just makes it
look easy! -
I admire the enthusiasm of folks going out and getting a motorized dish just based on what they've read.
Installing it on a roof can be frustrating without some experience.
To get the install correct, you have to master so many things at once.
If any one of the dozens of little gotchas are wrong , you get no picture... and wonder why?
The Conservative Approach to FTA Motor Install:
1). learn the configuration options on this new FTA receiver.
read the manual - ask questions - this terminology is new.
(optional):
If you have Dish, ya might plug it into the wiring for that and get your feet wet.
The Mercury II isn't supported by the hack crowd, so the most you'll get is NASA, Angel, and a few barker channels, but you'll learn how the receiver works.
2). install your dish without motor,
at ground level, to get a feel for it
Aligning a dish is tricky.
But now that you're familiar with your receiver, you can concentrate on finding a signal.
This will also give you a shake-down run with your cable, grounding blocks, and other general hardware.
Some years back, when Radio Shack and Walmart both sold self-install kits and Dish receivers, I helped a buddy put up his little dish.
We bolted it to a free-standing ladder in his back yard, just to have something to work with.
Even thought he's a machinist and used to working with delicate and touchy tools, he was amazed at how critical the alignment was.
(I made him do it all so he'd have hand's-on experience)
FTA alignment is more precise than Dish aiming.
3). I would suggest ya take a few days and aim the fixed dish at several satellites, getting more familiar with your receiver and the programming available.
4). for your first motor installation, a ground level site (or go over and use Linuxman's flat roof) would be a good place to get your feet wet.
Read and understand your motor's manual. Make sure you know what it's saying.
Look on Sadoun's site for motor install info - it's well documented there.
Get the PDF manual for STAB motors, and look at the pictures late in the book for how to correct inaccuracies of tracking.
(re-read this section again, and understand it!)
You don't have to have a ground location that sees the entire arc.
Any install-experience will be worth its weight in gold when you are up on your roof for that final round. -
FTA installs aren't really hard to do. They're just tricky to learn... the first time.
No one wants you to get frustrated and throw the stuff out the back door.
There's probably one user a months who shows up here on the forum asking for help after going it alone and failing.
The members here walk 'em through it and they succeed. You will, too.
. . . and without even raising your blood pressure! -
