If Shaw works like Bell does, you should get a free LNB & free install if you purchase new HD channels that require this LNB.
If you are a Home-Away-From-Home (HAFH) customer, you should get another new LNB for free too, for your 2nd location.
However, having said that, most HAFH customers already have their 2nd dish already equipped with the new Triple XKu LNB.
The trouble will occur if any of their family members have a receiver on the same account programmed for the old Dual LNB. When the Primary location receives a Triple LNB, the locations with the Dual will stop working.
They will have to purchase a Triple for their dish, and these cost upwards of $100 inc. tax.
