Rotatable 200M antennas that are half a meter wide!


According to the following IEEE paper:

http://www.ttr.com/TELSIKS2001-MASTER-1.pdf

A 75m 6" dia. 4 tpi Texas Bugcatcher coil has a
VF of around 0.024 on 1.9 MHz. A self-resonant
160m dipole made from such coil stock would be
only about 6 feet long.

That may be true Cecil but it is a lousy antenna.
The conclusion of the article infers that lumped loads
can be equated to distributed loads which we all know
is an error.
One of the requirements for radiation is that the
radiators surface is not enclosed. A lumped load
does not accomplish that.Usually when Richard
posts on a thread it is usually a death knell
for any further communication.
With you replying to him in some way this thread
may stay alive for a while. You will notice that
he did not identify "it" that apparently was used
before Marconi came along.He also talks of long discussion
of this "dipole" of Queen Victoria which as you know is a
figment of his imagination.A replacement for it.
He is just a childish idiot looking for some sort
of recognition who cannot communicate.
