Fourteen percent off-center fed antenna.
3. The inverted L antenna. The inverted L antenna (figures 46, 50)
is a half wave or a quarter wave in length. It is end fed. It uses
a single wire feed that can be a quarter wave in length, or may be
connected directly to the whip binding post.
inverted L is 2500 ohms.
An antenna tuning unit is needed to load
this antenna, or the transmitter must be able to load antennas over a
A counterpoise may be used to reduce ground
The counterpoise should be 3 to 4 inches above ground
using tent pegs.
However, the antenna will perform without the
The counterpoise ensures that the ground reflected
wave is not absorbed but adds to the direct wave.
