When not in the shack I leave the aerial floating in the hope that it will
be charged to the voltage potential of its surrounding so that lightning
won't  "see" it.
Or is that a misconception?

When grounded it could act as a lightning conductor and it certainly can't
stand up to a stroke without causing heavy damage.

Hi Dick es all,
I`m 30 years on the "wireless" - job. I never grounded lw - antennas, neither short ones nor long ones (400m straight or 1600m rhomboid). "after operation you have to disconnect lws (incl wire dipoles) from all equipments but never ground them" was an order of my father. that makes an other plus 30 years of experience. the vicinity of the end of the wire (feeder) must be free of objects for one metre.
the sense was, ungrounded antennas (litze) never go down in conductivity.

but if there are children or laymens (xyl) arround you have to ground them!

regards
