At the weekend, I tried using a tuned radial instead of my earth
stakes. This followed Finbar's recent success.
I ran a single wire up the garden - about 20m - one metre high. I
tuned it by using it as an antenna tuned against ground and
adjusting a series loading coil for resonance. The normal antenna
was then reconnected and the tuned radial used instead of earth.
Unfortunately, I could not get any current into it at all, even though
the antenna resonated at about the right frequency.
