Skew-Planar Wheel Antenna - Revisited, by VE3BYT with VE3KL.
This antenna, constructed by VE3BYT, was built
for the beacon VE3WCC on 903.370 MHz in Ottawa, Canada.

attachment of the coaxial feedline, the connection and the
center hub are coated for waterproofing.
In the 903 MHz antenna, the lower ends of the elements are
soldered into a copper pipe cap.
In the 440 MHz version the elements terminate in a (soldered
together) stack of lugs.

Skew-Planar Wheel Antenna at 1296 MHz was constructed by
Peter Jago, VA3PJ, using an inverted female SMA connector.
The antenna is mounted on
rigid coaxial cable.
This one is
built for left-hand circular polarization.
David Conn, VE3KL, has done an extensive analysis
of the Skew-Planar antenna.
It produces circular polarization, and has an omnidirectional, low

or 12334 / F (inches) long.
This antenna is broad in frequency response. In practice, element
lengths are not supercritical.
