E-field probe RX antenna

Years ago, I would have built my own, but these days my fine motor skills are not as good as they once were. So I have bought a PA0RDT miniwhip RX antenna. It should arrive next week.

Suitably mounted in the garden, if should be quite an effective LF and MF RX antenna. This "season" I want to concentrate on 137 and 472kHz RX. I might also try top-band.

Roger,

You may need to do a bit of work to get the best results and minimum noise.

Yes, I am aware, but thank you anyway.

I like the small active antennas, very useful for propagation monitoring over a wide frequency range.
I used an old German 1m while for a while, till I blew it up, probably by TXing too much power near it.
It needs to be relatively clear of nearby metal structures, and the house, but I heard a lot on mine in the time it worked.
