Where does LNB look at the dish?

[billinmidmich]

Lets say you have a dish that is recieving 110,119, and 129. The LNB for 119 is looking at the center of the dish....I assume. The 110 LNB sits to the right of the 119 LNB and where does it look at the dish, to the right or left of center? Same for 129?

Standing from behind the dish the 110 hits the right side, 129 hits the left side.

thanks....trying to set up a larger dish for better reception but can only get one sat. I need to fab a mount for it. The LNB's are not spaced right , I guess. Just trying to get 110 and 119 and can only get one or the other no matter where or how I point the dish. Wasn't sure to aim them straight at the dish or crossed.

That one is beyond anything that I have tried. I assume you wanted better reception on the 129? You could always use a single dish to point at the 129/61.5.

Have you played with the skew on your larger dish?

I'm not an engineer and don't know geometry either; I'm somewhat of a backyard mechanic, and close my eyes when I shoot pool.

Similar to the Toroidal and other multi-orbital location satellite dishes, I thought the Dish 500, Dish 1000, and SuperDish all had a different shape to it then regular single orbital location dishes; which helps to make it easier to pick up two orbital locations.

rcdallas may be correct that it hits the right side for 110. I don't know where it hits!
However, in regards to your comment about "Wasn't sure to aim them straight at the dish or crossed." here are some other items to play with.

On a Dish 500.
The 119 signal comes from the west of center (right side) and reflects to the LNBF on the east of center (left side).
The 110 signal comes from the east of center (left side) and reflects to the LNBF on the west of center (right side).

On the Dish 500 when using it for 119 and 110, the azimuth is computed as if the actual orbital location was at 114.5 degrees (in between the 2) and likewise for the skew. I haven't played with the Dish 1000, but suspect it aims at the 119.5 orbital location (halfway between 110 and 129), as well as the skew. However, you may find you will have to twist/turn each LNBF on the larger dish to properly adjust the skew.

It sounds like your goal is to use one dish for 110/119/129, but just go larger. Then you may want to consider the Dish 1000+, unless you are looking for an even bigger dish.

I believe rcdallas suggestion of using two dishes would be better and the easiest.
One option would be to use the larger dish for 129 only, then re-peak your Dish 1000 for 119 and 110.

I just hope the SuperDish 121 Repoint Kit will be out soon.
