I've flown with an SNG Satellite terminal as my luggage (not fun, I don't recommend it).
If you're flying with any of this kind of gear internationally, I strongly recommend that you get a Carnet for it. This is basically like a passport for your gear.
When you leave Canada, you have to go and find the Canada customs at the airport as you leave, have them sign and stamp the paperwork. When you arrive at your destination, the country of import as a sheet they stamp and sign. When you leave to return to Canada, you then get a third sheet stamped on re-exportation, and finally, a fourth sheet gets stamped as you re-enter into Canada. A real pain in the arse, but worth every penny when you're in this biz.

They're sticklers for having every paper stamped (this can become more important if you travel to officious countries like India) so make sure you go through the entire procedure every single time.
