The type of antenna that is used will greatly affect
the performance of the equipment. Use a properly
'adjusted antenna, of good quality, to enable your
equipment
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
recommended.
Match
the
impedance
of the
coaxial cable and that of the
antenna so that the
SWR is less than 1.5. The
protection circuit in the
transceiver will activate if the SWR is particularly
poor (greater than 3 ).
High SWR
values wili cause the transmitter output
to drop.
