Let's face it, you know those TV remote trucks you see? (here in NYC, all the
time) - what do they use on that mast? Hardline! The trick is, is you look,
is it makes a BUNCH (a BIG bunch) of turns around the mast so that the wire
doesn't move all that much each time the antenna is raised/lowered/turns (That
and the fact that they are willing to replace the cable more often than most of
us)
