Hi Stewart,

The answer to that is driven by the perceived problem. In a nutshell,
if you don't have a problem, you don't need the balun (or choke).

Knowing that you have a problem is another matter; but if you don't
know what the problem is (the perception), you wouldn't know if it got
fixed either.
