Andre, I too have the Tracstar SV-360 unit and NO it does not support the HD signal. It supports the Digital Broadcast Signal to your HD TV's but NOT HD, partly because the dish is not the Eliptical shape.

I get HD to my TV's via my Off-Air Roof antenae, or electric rabbit ears if you will, and use the Satelite for Digital quality Direct TV.

I believe Dish TV is the only carrier that can give you HD TV thru a Satelite Dish, but don't remember whose dish you need?

Check out this website then call them to get better answers, http://www.satellitesinmotion.com/1.html?sm=57463 I spoke with Debbie for my install.
