noCan I use a direct tv reciever on my old Shaw dish & LNB?
irrelevant. Shaw LNB is KU Band (11.7-12.2) so even if he has the original flashlight LNB the frequencies dont matchThere are a few Shaw dish configurations. Which one do you have?
DIRECTV receivers are also varied; legacy, HD and SWiM-only. Which one are you dealing with?
In any case, a Shaw dish cannot be used to receive DIRECTV HD programming.
