Default Classic Shortwave Antenna for a Classic {Tube} Shortwave Radio / Receiver

...


From the description I am unable to determine the antenna type. If I
was to take a guess that both sets of elements are the same length and
that they are supposed to be spread out in a "X" shape then this is an
antenna designed to couple very strongly the space around it. The
result of this type is a comparatively high voltage output. This is
useful for a radio with poor sensitivity. This type will generate a
stronger voltage for a signal for which it is cut than a dipole.


It looks to me like a garden-variety bow-tie dipole. It would perform like
a simple dipole, just a little more broadbanded.


This antenna type is appropriate for tube type receivers as rain, snow,
sand or just blowing wind conditions will have a stronger tendency to
generate a larger static charge compared to other antenna types. This
could be a problem for solid state radios. You would want static
protection for a solid state radio with this antenna.

Tube radios need static protection, too. The input coils open up, even if
the tubes remain unharmed.
