can't see why it would matter ... i would guess that they are linked to your account number - not your address .. good question though ... maybe someone who had done this would have a better idea.
edit - what time is your install ? What equipment/package are you getting ?
Is it wrong that i am excited for you ?
Ever since i made the switch it is like I'm a kid that just found a store that gives out free candy - and each time someone else stumbles across this "secret" i can't wait to see their reaction to it ...
Make sure they install the 2 monopoles to brace the Slimline. And make sure they tighten down all the bolts. My original Slimline installer didn't and my dish got blown slightly out of alignment and I had to have it realigned in January. The 2nd guy did a good job as I get strong signals even in high winds now.
