Members,

My backyard is in the city 8 x 8 m.  My intention is to do some experiments
on 472 khz.
Ready: RX converter 0-500 khz 10 mhz osc. and K3, RX ant. pa0rdt whip and
receiving loop

TX: GW3UEP 100 watt, RF meter, and variometer 30 uh -600 uh

Now i'm looking for a antenne. Found a article from Finnbar EI0CF and Alan
G3NYK about the spiral toploaded vertical.

Has any body tryed this antenne, is the original article availble.
What is the distance between the wire's  of the spiral?
Also talking about a double spiral?

So who is gone help me out  ore has some better suggetions for a antenne in
my backyard
