Rapid Deployment Broadband Dipole Antenna Configurations
Horizontal Dipole
The horizontal dipole has maximum gain on the broadsides of the antenna and
reduced gain along the axis. Height above ground affects radiation angle. Lower
heights give higher angle radiation, better for NVIS (short distance). Higher heights
give lower radiation angle, better for long distance communication.
Inverted V
The inverted-V has a more omni-directional pattern than the Horizontal Dipole, with
lower maximum gain. The ends of the antenna should be at least 0.5m above
ground. Suitable mainly for NVIS and medium distance.
