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).
