Well, some have done it on even smaller dishes, but from what I've read, 1m and certainly 1.2m are better choices (if you don't have a 2m/6ft dish)

This summer I bought this dish and the C/Ku LNB. I have had little luck with either C or Ku band reception. Anything in the upper end of C band is very low signal strength and my RX's won't lock to it. From what I have seen on the spectrum monitor, I'm getting way too much adjacent satellite interference. I'm trying to find time to play with LNB and scalar ring positioning. Anyone else figured out how to tweek this dish/LNB combination?

For a better discussion of the problems, and solutions, I'd refer you to two threads below, by Satcom1, and Linuxman.
The Linuxman thread has a number of good strong target birds and transponders.

Several members have various 1.2m dishes (just not this kind) and are successful on C-band.
Also, a conical scalar may be useful.
Though, with the GeoSat's short focal length, maybe not . . .

If you want to get into the discussion more, I'd start a new thread.
I promise it will get some attention!
Then, depending on the outcome, return here and post a link to it.

Thanks, I'll take a look. I'll report any luck I have with the dish when I get some time to play.

While I am at it let me give everyone a little review of the GeoSatPro 1.2 meter dish I used for this project; The reason I initially purchased this dish for my mini Bud was the they way it was manufactured. It looked very sturdy and had an elevation adjusting bolt on the mount that was very similiar to what I fabricated and added to the Winegard 76cm DS2076 dish.

What I found out is that this dish is very well made, very sturdy and the dish pan has some meat to it that will keep its form for extended use. The elevation adjustment using the bolt at the lower portion of the dish mount allows for very precise fine adjustments (works great). The side struts connecting the LNB support arm to the dish pan keep the LNB positioned even in windy conditions. The elevation scale is easy to read and makes initial setup a breeze. When connecting the dish to the motor tube I folded over a large sheet of course sand paper and wrapped it around the motor tube, so that the grit contacted both the motor tube and the dish mount. This trick holds the position of the dish to the motor securely in place allowing for the use of even the smaller diameter motor tubes. The addition of sand paper will keep the dish from spinning or twisting on the tube (trust me this trick works great and would take a couple of pipe wrenchs to move the alignment once set).

ACWxRadar also has this dish, he added an additional U bolt to the dish mount, the dish has holes to acomadate three U bolts but only comes with two. The addition of the third U bolt also helps to secure the dish to the motor.

I give this dish a 10 for its performance and durabilty. I highly recomend this dish to anyone contemplating the purchase of a 1.2 meter dish.
