Any of the common antenna systems designed for use
on the high frequency amateur bands may be used with
the TS-440S provided the input impedance of the
transmission line is not outside the capability of the Au-
tomatic Antenna Tuner. The transmission line should
be coaxial cable. An antenna system which shows a
SWR (Standing Wave Ratio) of less than 1.5: 1 when
using 50 ohm coaxial transmission line, or a system
that results in a transmission line input impedance that
is essentially resistive, and between 20 and 150 ohms
will take power from the transceiver through the AT
unit.
2-2-4. Key connection
Your key should be connected as illustrated in the
figure below. When using an electronic keyer, make
sure that polarity is set for pasitive. Always use shieid-
ed line from the key to transceiver.
Before connecting; check that the
potarity is correct. The KEY jack
provides +5.5V. Use shielded
cable.

2-3. MOBILE
Being compact in design, this transceiver is ideal for
mobile operation. Satisfactory mobile operation is
achieved through proper power and antenna connec-
tion, and thoughtful transceiver installation and ad-
justment.
2-3-1. .Mounting bracket installation
Secure the TS-440S under the dashboard using an op-
tional MB-430 mounting bracket. As an alternative, use
strapping, making sure that the TS-440S will not slip
out of place while operating the vehicle.
Notes:
1. Do not install the TS-440S near the heater outiet.
2. Allow sufficient space behind the TS-440S to en-
sure proper ventilation.

. When charging your vehicle battery, or when jump-
starting a dead battery, ALWAYS disconnect the
power cable fram the back of the transceiver, or
damage may result ta the transceiver.
Connect the TS-440S power cable to the battery ter-
minals, with ion to current fi and
noise prevention. The maximum current drawn by the
TS-440S reaches between 18 and 20A when trans-
mitting. Therefore, the cable should be made as short
as possible, using the specified fuse. Also, canfirm that
the power system of the car {including the battery and
generator or alternator) will handle the increased load
of the TS-4408.
