TORNADO TUNER©
The Tornado Tuner© is a
precision variable inductor
that can be remotely adjusted.
This patented system varies
the inductance by mechanically
expanding and contracting a
coil and has no wiper contacts
to short or wear out.
The Tornado Tuner© was
developed out of a need to
expand the useable bandwidth
of 1/4 wave 80 meter dipole
antennas. The Tornado
Tuner© is available for both
Dipole antennas as well as
vertical antennas. Custom
versions can also be built for
your application.
