Hello Lowfers & LFers,

My good wife gave me Volume 7 of the ARRL Antenna Compendium
as one of my Christmas gifts.  On page 3 is an article which describes a
very clever way of placing inductive loading at the top of a tower which
is part of a top loaded monopole. The author is John Belrose, VE2CV.

It's done by placing an insulated conductor inside the upper portion of
the tower.  The top of the conductor extends above the tower slightly
and has the top loading attached to it.  The lower end of the conductor
is connected to the tower to form an air-insulated coaxial line.  Moving
the position of this lower connection varies the length of the coaxial line
which in turn varies the inductance.

Has anyone here heard of this previously and/or tried it?
