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!".

73, Dick, PA0SE
