Antenna
The type of antenna that is used will greatly affect the per-
formance of the transceiver. Use a properly adjusted anten-
na, 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-8U or 8D-2V for this
connection. If the antenna is far from the transceiver the
use of low loss coaxial cable, such as RG-8U is recom-
mended.
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:
For protection against fire, electric shock, personal injury,
or damage to the radio, use a lightning arrester in your
antenna lines.
