I generally agree with Toban's comment but I found that our 600 series PVR seems to have a cut off at a signal strength of about 60, below that it gives a red light and no reception, I don't recall this limitation on our older 200 series receiver. I notice this sometimes as we have the Shaw LNB mounted on our internet satellite dish (which is aimed at another satellite 99W). Because the skew angle is different for 99W compared to the Shaw satellites I get a signal degradation on Shaw. For the vast majority of US destinations there should not be a problem getting a minimum 60 SS with a "pure Shaw" dish. I wonder if it would be an issue in Mexico though. By the way, the "100 miles south of the border" comment refers to the loss of the HD channels on the third (new) satellite that Shaw launched, most if not all these channels are presently duplicates of those HD channels existing on the other sats. Who knows how Shaw may shuffle things in the future though! For now your hockey and curling is safe!
I changed over to the 630 receiver and new LNB in the summer of 2012 and used the combo in the southern USA in the winter of 2012/13 as far south as Yuma AZ and it worked.
