I do understand but some persons cannot be told. It
depends how it is configured/installed, height above ground , environment etc

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.

That's an important point that is often overlooked or ignored. A mini
