adit, save yourself some $
Put SHOW-HD on, then put the signal strength meter on.
WHile someone is watching the meter, use a 7/16" wrench, loosen the 2 clamp bolts and SLOWLY turn the dish left and then right.
When the highest signal strength is found, TIGHTEN the two bolts.
Then loosen the two bolts on the side that allow the dish to go up and down.
SLOWLY raise the dish, did the strength increase or decrease?
LOWER it slowly and check the strength.
Once you find the highest signal strength, tighten the bolts.
A word of caution - Shaw receivers are slow at reacting to signal strength, so you have to be patient between adjustments. It can be 2 - 3 seconds for the number to change after moving the dish. Also, before attempting this procedure, be sure to mark the dish's original location using a black marker AND check the elevation # on the guage.
Good Luck! It's not that difficult.
