For the low cost of the Avenger ($10 US and free shipping to my wife's US mailbox) I thought I would give it a try, considering some posts on some forums have liked the Avenger PLL321S-2 PLL over a GeoSat. Other opinions were that the GeoSatPro SL1 PLL LNB was just as good.
After figuring out that I had to change the LNB from 10750 to 9750/10600 or to 10600, I found that the reception was just the same. I was hoping that it would be a little better and I would get back the Oklahoma PBS on 125W or that COSI on 103W would be above the threshold, but no such luck.
I'll just leave the Avenger in, as it made NO difference
