Sloping Dipole
Radiation with the Sloping Dipole becomes somewhat asymmetrical, with increased
gain in the direction of the lower end of the antenna, and reduced gain towards the
higher end.
Single Ended
For rapid deployment, with reduced but still acceptable efficiency, the antenna can
be operated single ended. In this configuration, one side of the antenna (labelled
“antenna”) is unwound to the desired frequency and tied to an elevated structure.
The central balun should be located close to the ground, and the remaining side of
the antenna (“earth”) partly unwound (5 to 10m) and stretched out on the ground
below the radiating element.
