101/95 Dish pointing to 72.5

[satellite-noob]

Hi!

I have a problem, but I do not understand why. I have an oval DirecTV WorldDirect dish with 2 LNBs. The dish was pointed towards 101 satellite and I was expecting to get signal from 101 and 95 satellites, but instead I am getting perfect signal from 101 and 72.5 Did I get the wrong dish? The manual that came with the dish does not even mention the 72.5 - it's all 101 and 95. My old dish that I left attached to the old house looks identical to the new one I bought on eBay. Yet the old one picked 101 & 95.

I have been thinking about this and the only explanation I have is that the same dish can be "configured" to work with either 95 or 72.5 sat. It seems like a simple geometry question, but I if it is a simple geometry I am puzzled how the same dish could work in Boston and San Francisco, or San Francisco and Dallas. I suppose they could not and DirecTV would be sending different configuration of dishes to different regions. Anyway my only question is how do I get the right dish that will pick 101 & 95 sats in San Francisco Bay Area? Thanks.

The dishes can and do have multiple focal points. I would try to repoint the dish a little further to the west and see if you can pick up the 101 again. It could also be that you don't have the 95 LNB set up in the correct slot for your area. On the back of the 95 assembly, there should be a slot with three holes in it to adjust the focal point of the 95 sat.

There is no way you're getting 72.5 on the 95 LNB. They're 2 different polarity setups

95 is a linear satellite
72.5 is circular

If anyone is interested in he resolution of this. It turns out the oval 2 LNBs antenna needs to be pointed to 101. The other LNB is automatically pointed to 95. However you need to run auto-info process on your DirecTV box to make it work. Making all the same configuration choices does not work.
