3.3 Balanced vs. Unbalanced

Antennas

The distinction

between balanced and

unbalanced antennas

is that balanced

antennas are

electrically balanced

at the feed point while

unbalanced antennas

require an RF Ground

to provide the balance. Dipoles and loops are typical

balanced antennas.

Unbalanced antennas need an RF Ground such as a radial

wire system or a

counterpoise to create

electrical balance. They

depend on the quality of

the ground for a maximum

radiated signal. Without a

good quality ground,

unbalanced antennas will

cause interference, RF in the radio room, and radiate

poorly. Long wires and verticals are typical unbalanced

antennas.
