My backyard is in the city 8 x 8 m.=C2=A0 My intention i= s 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.

Also talking about = a double spiral?

So who is gone help me out=C2=A0 ore has some= better suggetions for a antenne in my backyard
