Hi Horst, Jim, LF,

Same here, I have used a PA0RDT Mini= -Whip active antenna for a good while now & it's performance is ve= ry good right down to 10kHz, may even go lower if I knew what to look for= !!!

My online grabbers use the Mini-Whip antenna.

73,

Gary - G4WGT.

Hi Horst

I've just installed one of Roelof Bakker's (PA0RDT) active mini wh= ips and it
is excellent at my QTH. =A0Just my view, others may have different experie= nces

With best regards

Subject: LF: Best receiving antenna wanted

Hello,
now that I am happy with my selectiv level meter Praecitronic MV-62 I am looking for the best receicing antenna.
Especially I am interested in 400khz, 136kHz, 72kHz and below 22 kHz. With=
my 40m longwire reception is not good enough and with a frame antenna of 900m copper wire it was disappointing, too..
I think, an active antenna for 0 to 500 MHz would be the best for me - but= I
am looking forward to any other idea.
