I found this about ANIK G1 and wanted to share my experience. I am on the VA / NC border. I could not get any G1 channels with the 75e from Shaw, I tried a 4 foot, no go, I tried a 6 foot, but it would only get one transponder , number 16. So then I installed an 8 foot offset Prodelin in order to receive G1.
I was shocked at how the signal can differ from hour to hour with the G1 transponders.
I have gone through several situations with trying three different F1X, two different 60e and one 75e LNB’s.
I found out that using the 4x8 powered switch made the signal quality a little better. I just used an old DirecTv switch.
So, this is the end result. The new style F1X, with the long neck, works when using a conical scalar connected to the very end. Also, adding the 111 LNB on the same dish caused interference for the G1 signal. I accidentally discovered that when the 13v side was disconnected, that the signal was a little better on the horizontal transponders.
So, since I the most channels that I wanted were on even transponders, I decided to leave it that way. I connected the 75e dish for the vertical transponders from 107 (missing all G1) and the 111.
My end result for the beset performance: F1x with a conical scalar on the very end on an 8 foot offset with one cable going to multiswitch, the 18v volt side. Three cables going to a 75e dish with the triple sat Shaw 75e LNB. Again, I do not get any odd G1 transponders this way, but I get transponders 13 and 14 almost all the time and 16 all the time.
I wish there were a better LNB that I could use so that I could get both horizontal and vertical without the 2 interfering with each other! From time to time, I used to get transponders 5 and 8, but this was with a F1X that went bad after around a year.
I wish that we could use one of the setup listed here

But, it looks like only the way to go for the setup with a residential receiver would be the $1500 option that might or might not work. I know that many say that those LNBs cannot be used with a residential receiver, but if you read the following information, I think that I might indeed be possible.

I wish there were a way to combine the 4508c with another LNB via diplexer in order to use the 4508c. If I knew more about making notch filters, I would make one that would pass the G1 signal only, and one that would pass the F1 signals only, and then combine the two.
