Dickman-Klapper


#1

I was SWLing yesterday and came across a /MM station chatting to a USA station. Both seemed to be ex navy talking about a Dickman-Klapper antenna and how wonderful it was. I gave a call but they did not hear me. I did a Google search and zero hits. Does anyone know what the design of this antenna is? Or did I mishear?
Thanks

Hi Mike… it seems that this name lead to a German Company named:
Dieckmann & Klapper Gerätebau GmbH, Hamburg

But I don’t have further informations about.

Yes I can see the design and how this multi vertical is. Two rings joined by multiple verticals. I will try and find details :sunglasses: !

Thanks Bernhard. I have now found quite a bit on the net including its history going back to 1922 with first amateur radio transatlantic tests.

Best wishes for Christmas.
