Since you said you are using a tuner, you don't care if the line
impedance is changed moderately by the proximity of the tower.
You are probably fine if the spacing to the tower is 2 or 3 times
the wire spacing of the line. Try to keep balance by putting
Twist it! Ladder line, TV ribbon, parallel wires should be twisted.
Twisting the wire will not prevent the proximity to the tower
from lowering the impedance (it will always be lowered).
Not that it matters.
That not twisting will, or can drastically change the balance between
conductors does matter though for pick up of noise/interference and
inducing RF current in things other than the tower. If those other
things have a rusty bolt or joint uit can lead to RFI.
