INSTALLATION
ANTENNA CONNECTION
An antenna system consists of an antenna, feed line,
and ground. The transceiver can give excellent
results if the antenna system and its installation are
given careful attention. Use a properly adjusted 50Ω
antenna of good quality, a high-quality 50Ω coaxial
cable, and first-quality connectors. All connections
must be clean and tight.
After making the connections, match the impedance
of the coaxial cable and antenna so that the SWR is
1.5:1 or less. High SWR will cause the transmit
output to drop and may lead to radio frequency
interference to consumer products such as stereo
receivers and televisions. You may even interfere
with your own transceiver. Reports that your signal is
distorted could indicate that your antenna system is
not efficiently radiating the transceiver’s power.
Connect your primary HF/ 50 MHz antenna feed line
to ANT 1 on the rear of the transceiver. If you are
using two HF/ 50 MHz antennas, connect the
secondary antenna to ANT 2. Connect VHF
(144 MHz), UHF (430/ 440 MHz), and 1.2 GHz
(TS-2000/ TS-B2000 Optional) antennas to their
respective antenna connectors on the rear of the
transceiver. Refer to page 13 for the location of the
antenna connectors.
◆
Transmitting without connecting an antenna or other
matched load may damage the transceiver. Always
connect the antenna to the transceiver before transmitting.
◆
All fixed stations should be equipped with a lightning
arrester to reduce the risk of fire, electric shock, and
transceiver damage.
Note: The transceiver’s protection circuit will activate when the SWR
is greater than 2.5:1; however, do not rely on protection to
compensate for a poorly functioning antenna system.
Connect all accessories to the transceiver {pages 3, 94}.

GROUND CONNECTION
At the minimum, a good DC ground is required to
prevent such dangers as electric shock. For superior
communications results, a good RF ground is
required, against which the antenna system can
operate. Both of these conditions can be met by
providing a good earth ground for your station. Bury
one or more ground rods or a large copper plate
under the ground, then connect this to the transceiver
GND terminal. Use heavy gauge wire or a copper
strap, cut as short as possible, for this connection.
Do not use a gas pipe, an electrical conduit, or a
plastic water pipe as a ground.
LIGHTNING PROTECTION
Even in areas where lightning storms are less
common, there are usually a limited number of
storms each year. Consider carefully how to protect
your equipment and home from lightning. The
installation of a lightning arrestor is a start, but there
is more that you can do. For example, terminate your
antenna system transmission lines at an entry panel
that you install outside your home. Ground this entry
panel to a good outside ground, then connect the
appropriate feed lines between the entry panel and
your transceiver. When a lightning storm occurs,
disconnecting the feed lines from your transceiver will
ensure added protection.
