Without a ground connected to a battery-operated portable receiver,
for example via the earphone socket, the input impedance at the
antenna socket is umpteen thousand ohms.

So it doesn't matter very much what you do about the whip.

But you knew that before you asked the question. So why ask it? ;o)

I would guess, in your younger days, you were a gifted, over-active
little boy who asked questions with a motive always different from the
obvious one.

It is indeed a very useful technique for gaining information about
which the subject may be reluctant to divulge. Perhaps you should have
been employed as a WMD inspector to discover that none existed years
before Saddam confessed that he never had any and had never possessed
the facilities to manufacture them.

But it's a dangerous occupation. The senior British WMD Inspector
committed suicide shortly after blowing the whistle - or so the story
goes. ;o) ;o) ;o) ;o)

Whilst on the subject of whip antennas you may be interested to run
program WHIP_1 which analyses performance, from transmitter to
receiver input, of a typical vehicle-mounted whip + un-un transformer
+ coax line + receiver.
