Not a bad practice to adhere to when bringing coax transmission line into
a building/house but does nothing to alleviate the balanced to unbalanced
situation at the feed point.

high current lightning. Experts even suggest as little as a single turn
coil in a coax line helps. What the commercial stations do, though, is
NOT put the coil at the feedpoint. The coil (or "drip loop" as it is
sometimes known) should be positioned near where the coax enters the
station with the coax shield grounded prior to that point. The theory is
that the resistive inductance to lightning is sufficient to discourage it
from continuing into the station and, instead, it takes the direct path
to the ground provided by the shield-to-ground lead.
