True.  However, you have to keep it away from metal and other wiring -- at
least twice the width of the line.  This is because the electromagnetic
field extends into the air around the conductors, whereas with coax it's
contained within the shield.

With coax you'll probably want a preamp at the antenna to make up for the
line loss.  You have to weigh this added expense against how difficult
it'll be to route the twin lead.
