2. Otherwise think about where you want DirecTV to think your dish is located. Probably it should be either in the New York or Los Angeles area, since those network feeds are on the national beam. Vancouver might be able to be in the spot beam from Seattle, so that also might be an option.
3. You will have to buy your own receivers, dish and pay to have it installed. You can use one of the online calculators to set your azimuth, elevation and tilt, rather than use a zip code method.
4. You also need a VOIP phone like Vonage or Skype to make a call to DirecTV to activate your service once your dish is set up.
Once you get it going, its fantastic. You have lots of HD channels like Fox Business that isnt available in Canada as well as the old favorites like ESPN and HBO. And its much cheaper too with the elevated Canadian dollar. Enjoy.
