Antennas — Antenna Feeder
Information on Antenna Feeder
A dipole is a balanced antenna since it has a
current on both legs. A monopole is an unbalanced antenna
with a current only on one leg and the other
grounded. A balanced antenna should be connected to a balanced
antenna feeder and an unbalanced antenna to an
unbalanced antenna feeder.
The feeder between transmitter or receiver
and the antenna must be accurately matched to the antenna
input impedance for maximum power transfer. This can be achieved
by using an antenna feeder of the same
impedance as the antenna or by employing one of the
many matching devices available. Antenna feeder lines commonly
used are the coaxial cable (50-80 Ohm) and the two-wire
open line (300-700 Ohm).
