Rik, LF,

I have run my 300 watt class D Tx at 1 watt ERP on 500kHz & my Mini-Whip is only about 4 metres away & is still working OK. Very solid design.

73,

Gary - G4WGT.

Roelof,

I cannot agree, a Belgian beer can will provide at least 10dB better SNR ;-)

Now serious: I have been thinking about a simple but good RX antenna for LF, MF and the lower HF range and you mini-whip seems the right solution.
But will the preamp survive when pumping a few 100W into my 500kHz TX antenna (lazy-L) that will be only 25m away ?

73, Rik  ON7YD - OR7T


Quoting Roelof Bakker <[email protected]>:

Hello Alberto,

I am not much in beer myself, but there seems to be a famous Dutch brand,
that I can recommend!

73,
Roelof, pa0rdt
