A Full-Size / Half-Space Antenna
Horizontally-Polarized / Omni-Directional
GAIN: -4.5 dBd
NOTE: These are just theoretical examples and do not fully represent reality.
In reality, a low 80m dipole radiates much more off of its ends. Never-the-less,
a trend may be seen here.
This good omni-direction radiation pattern makes the Halfback
a great general purpose antenna for 80m communications,
occupying just half the space of a full-size dipole.
I have only built this antenna once, only used it at one location.
It needs to be reproduced and tried at several other locations,
so that we can gather more experience on its performance.
