I have this Gospel LNB and I think it should be good for 118.7 and 119 right? Or is not good for either? I think it might be a Linear LNB actually. I got it with a Gospel 39" Dish I think back in 2006 or 2007

Nope, you need the special circularly polarized LNB.

Like this one, or one like it.

The other one is for the FTA satellites with linear polarization.

Something like this would work eh?

Does it have to have 2 outputs to get 119/118.7 on the same LNB?

That one will only get 118, it wont do 118 and 119 on 1 LNB, and you can't use 2 separate LNB's the satellites are too close to each other, (no way to setup the proper spacing) if you want to watch 118 and 119 you have to use the LNB designed for both on 1 LNB.

The 2 outputs are for using 2 receivers off 1 LNB, unless its a very old legacy LNB, then it may have a vertical and a horizontal polarity output to run to a switch.

Get yourself a CB2008A LNB. Will do the job.

Well I know which one to get but it costs $29.95+tax locally. I was hopping to get one for under $20 with shipping on Ebay, I guess not.

Actually this one on Ebay is the cheapest I guess

That is a good price and so is the shipping cost.

Word to the wise, don't go cheap on the LNB, you will have less heartache and more hair, also less time on the roof troubleshooting.
