The "centre" feed is 111, the offset (west side of dish) is 107.3. Theoretivally they could come up with a triple look LNBF for 118W. It works that way because the 107.3 reflects horizontally as well as vertically.
For a point of fact, I strapped a Dishnetwork LNBF to the east of my Shaw Direct LNBF, to get NASA TV from one of the Echostar satellites at 119, when it was FTA there. That worked fairly well.
Thanks for the clarification classicsat! It makes sense if 111 is the boresight. I was given the wrong info from a veteran Shaw installer who should have known better.
My next step was to climb on my tower and put a piece of tinfoil over one waveguide at a time, to see what satellite I lost.
