Try a 12metre fiberglass telescopic pole to support an inv L using wire size
1mm as long as possible. Use a matching network at the bottom of the
vertical part, coil in series to earth. Tap down coil for resonance, tap
coax up a few turns from earth end for best match, lowest swr, braid of coax
to earth. Use a couple of insulated radials lying on ground and connected to
coax earth. This method never fails to work.
There are other methods but the above is vy efficient, light and portable.

Dear all
I am hoping to be granted an NoV for portable operating on 500kHz. I
have parts on order for the GW3UEP Economy transmitter which will be run
on 12 Volts. Suggestions for portable aerials that can be set-up by one
person on remote and windy hilltops will be most welcome.
