Virgin is a cable TV provider and doesn't use any aerials. You're probably thinking of the coax cable that carries the live TV signals.
From the sounds of it, you're an existing V6 TV customer moving to a new home..
If so, and there's no existing co-ax point for the TV box, you'll need a manned install. You can either call in via 150, or wait for forum staff to pick this up and they might be able to arrange it.
