Hi Horst, Jim, LF,<= /p>

 

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

 

My online grabbers use the Mini-Whip antenna= .

Hi Horst

I've just installed one of Roelof Bakker's (PA0RDT) active mini whips= and it
is excellent at my QTH.  Just my view, others may have different experiences

With best regards

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.
