1.5 Antenna
The antenna plays the most important role in radio communication. If it cannot receive or
transmit effectively because of improper installation, even the most sophisticated transceiver will
be rendered useless.
1.5.1 Types of antennas
The most commonly used antenna is a long wire or a whip. Whatever antenna is to be used, the
antenna coupler can tune a long wire or whip whose total length is 7 to 18 meters (23.3 to 60
feet). Although a longer antenna is preferable when the radio is operated only on low
frequencies, use this size of antenna to ensure stable automatic tuning on all bands.
Long wire antenna
A long wire antenna in general provides better performance than a whip antenna, provided the
vertical part is long enough.
Whip antenna
It is easy to install and provides good overall coverage of most SSB frequencies. A whip
antenna is installed as high as possible, away from any nearby objects.
