No one is saving face or conspiring against a new idea. You can`t break
the laws of physics no matter how hard you try.

Antenna performance is based on lengths of wire in the air and the
currents in them. Take a broadside array for example. It is usual to
drive current through all the elements of a plane in the same phase so
that the fields at a distant point perpendicular to the plane of the
array are additive to make a large signal. It is a matter of radiator
lengths and currents.

Now consider a small diameter coil as a radiator. It is called an radial
mode helix because radiation is radial (perpendicular to the axis of the
coil). It has two extremes. If collapsed, the coil becomes a single
loop. If stretched to its maximum, the coil becomes a straight wire. If
controlled so that the same magnitude and direction of current flows in
all configurations, the straight-wire version of this coil should
produce the greatest radiated field strength perpendicular to the coil
axis in the far field.
