I have this thing lying around, in pieces and was looking at it today, thinking it might be a good suspect for a fixed dish project, been thinking about putting one on AMC1 ku since that one has the odd skew angle to it.
Anybody have one of these things that isn't destroyed like mine? I need the focal length, distance from lnb to dish-face. I still have the dish itself, and the d-tube with lnbfs attached to it, and some odd pieces of pipe left over from when I took it apart.
(it was given to me, and I dismantled it-using the mount and leveling mechanism on my motorized primestar-on-polar mount dish).
It looks big enough to work once I figure out a way to rig it to a mount of some kind, and fasten an lnb holder to it-at the right distance from the dish.
*If anybody doesn't know-these were KU/KA band dishes from directv, Has one big lnbf right in the front of the dish, that might be the ka lnb, and a couple of others kind of angled out to one side of that one. I don't think any of them would be usable for linear ku anyway.

You taking about this ugly thing?
Here's some more info, docs, specs, etc. AT-9, now discontinued.

Dish surface area dimensions: 25.5" (h) x 29.5" (W)
I'm guessin' it'd work similar to an average 30" dish.

Yes thtat's the one. The lnb support actuallly locks into the base of the mount instead of bolting someplace to the dish so it'll need some fabbing to hold the lnbf. I'll study some more on it.

I've had good luck with the AT9 by mounting an lnb so its face is at a distance of 17.5 inches from the AT9 dish surface. I start with the lnb aiming at a point about 0.5 to 1 inch below the top dish mounting bolts (a bit below the center point of the dish). The adjustable lnb mounts available from sponsors or on ebay work well - they have a good amount of adjustment front to back plus rotation for skew), and the bracket can be carefully bent to aim higher or lower on the dish surface. I drill a single hole at a point 1 7/8" from the end of the arm (after removing the original lnb's) and use a single bolt to attach the lnb bracket through a length of slotted DIN rail to the arm. This allows side lnb's to be easily placed for satellites 4 to 8 degrees off center. The photos show a couple of these dishes. I've been happy with these dishes, and I have used one successfully for AMC1 on a dish aimed at 97 with a side lnb aimed at 103.

Thanks Look thats the figure I needed. I'll have to start ground up to make a way to mount the dish (since I took mine apart and used pieces elsewhere). Thinking of just using an old primestar mount from one of the 1m dishes, bolt the dish to that, then finagle the lnb arm.
But I could probably get more out of the dish if I also rig a way to 'skew' the entire dish too.
Thanks for the tip, looks like you're getting good use out of your at9.
