3. Antenna
The type of antenna that is used will greatly affect the
performance of the transceiver. Use a properly
adjusted antenna, of good quality, to enable your
transceiver to perform at its best. The antenna input
impedance is 50 ohms. Use 50-ohm coaxial cable
such as RG-58U or 5D-2V for this connection. If the
antenna is far from the transceiver the use of low loss
coaxial cable, such as RG-8U is recommended.
Match the impedance of the coaxial cable and that of
the antenna so that the SWR is less than 1.5 to 1.
The protection circuit-in the transceiver will activate if
the SWR is particularly poor (greater than 3 to 1).
High SWR values will cause the transmitter output to
drop, and may lead to TVI or BCI reports.
Caution :
We recommend that you install a high quality
lightning arrestor in your antenna lines for protection
against fire, electric shock, personal injury, or
damage to the radio itself.
