Need opinions on this. Should I take a risk in buying this in hopes that it will hold my FTA motorized dish? It's a 31" but I may upgrade to 1 meter. What do you all think?

I don't think that NPRM will hold a 1 meter dish, as it is designed for the 18-24" DBS dishes. I have a couple of these designed for flat roofs, and they won't accommodate anything larger than 80-90 CM very well. They rely on a J-pole and mounting foot to attach the pole.

The one you linked to is interesting, its the only one I've ever seen designed for a pitched roof.

i've seen one locally for larger dishes so i know they are out there ....just gotta search .... it was for a 1 meter or 1.2 meter

NPRM project ?

31"? That's pushing it.
Motorized? I don't think so.
A 1m motorized? No way, Jose.

It clearly says it's rated for 24" dishes.
Doesn't even say what size it is.
But, you can see how it's built, and maybe work out the size.

So for the $80 it'd take to buy and ship it to ya, why don't you make your own?
Some old bedframes and a welder (or bolts 'n brackets) and you could make one for what? $25?
Plus cost of cement blocks, either way.

Start up a brainstorming project here, and get ideas (if you are interested)
I'm sure those more experienced with NPRMs will chime in , post pictures, and give encouragement. - :up

If you're not interested, maybe you can find a bigger one on Craig's list, your local Recycler newspaper, or elsewhere.
Maybe try eBay?
I prefer local, to eliminate shipping charges.

Not a bad idea, Anole. I also have an NPRM designed for the Superdish, but it too uses a J-pole with foot attachment. This type of mounting pole tends to sway too much with any amount of weight attached to it.

Tron -

Well, motorized dishes of any size are an off-center, off-balance masses, moving around making your life hell.
So, a sturdy mount with side-support struts is a requirement ! -
But, I have no doubt we could whip up a simple design for an NPRM that'd hold your SuperDish (even with a motor), using the existing J-pole and struts.
It's that peak-of-the-roof part that I don't much like.

I'll ask Linuxman to chime with his thoughts.
He's got several NPRMs on his roof.

I am about to find out how well a NPRM can hold a six foot dish! Hello Faye. Off to Lowes this morning for some more cement blocks. My 1.2 meter is also on one but I think it will be fine.

The pics that follow show what I have for my motorized Primestar 84e. I took the standard NPRM and modified it with the 2-3/8" schedule 40 pipe you see. I wouldn't use anything less for a motorized dish.

For a pitched roof, you could get two of these and have the pole in the center with the two NPRM mounted off each side.

Here are the pics:

Yep, Linuxman, that looks familiar I've got similar NPRMs for both my motorized and the fixed Channel Master on G-18, and they are rock solid.

Comptech, as far as hurricanes go, just remove the dish reflectors and you'll be fine in anything. That's what I did with both the Channel Master and my motorized setup when Katrina hit, and the mounts stayed put (and precisely aligned!) throughout the whole 140 mph. sustained/180 mph. gusts ordeal. I ended up with a much better LOS (nearly every tree in the neighborhood was leveled). If only my house hadn't flooded...
