CONNECTIONS AND INSTALLATION
■ Antenna
Most stations operate with a whip or long wire
antenna. However, these antennas cannot be
connected directly to the transceiver since their
impedance may not be matched with the transceiver
antenna connector.
R DANGER HIGH RF VOLTAGE! NEVER touch
an antenna while transmitting. It may result in an
electrical shock or burn.
