Total tosh Mal.  You clearly don't understand how E-probe antennas work.

I said recently that the wire connecting these type of mini antennas is in
fact the antenna. It was the same with the Partridge Joy stick of
yesteryears, the long connecting wire to the small loading coil was doing
most of the work.
There is no substitute for a real resonant antenna at the working frequency.
