Must 300 ohm feedline be kept completely clear of contact w anything?

How critical is it to mount twinlead feedline (300 ohm TV ribbon type)
so that it doesn't come into contact with anything? Obviously, with
You don't want unbalanced coupling between one side of the feedline and
something else. That would unbalance the feedline. You MAY not want the
impedance bump that comes with equal coupling on both sides, though that
might be tolerable if you're tuning the line anyway. And you don't want
lossy coupling of any kind.
