Dear Uwe and All,
Many thanks for your message that supports my own view.
Interesting that your father also advocated to leave the aerial floating.
That surprises me a bit because German broadcast transmitters in the
twenties and perhaps early thirties ended their daily transmission with the
warning "Bitte vergessen Sie nicht die Antenne zu erden!".

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
Uwe/dj8wx
