I'm planning on putting up a tower and a question I've always had is about
coax standoffs. Are they necessary?

No. If somebody used standoffs for coax, it was probably money wasted.
Coax can be secured directly to the mast or tower, coiled on itself, and
even buried (some types). It could even be tied in loose knots without
having its electrical properties affected. You just can't crush it or bend
it tighter than the bend radius specified for the cable.

Open wire line and TV twinlead must be kept away from metallic structures
and not coiled. That's what you use standoffs for.

In a few cases, some form of standoff might be used when the coax forms a
rotor loop, but such use is strictly mechanical.
