1 INSTALLATION

ANTENNA CONNECTION

In general, HF/ 50 MHz mobile antennas are larger and heavier than VHF/ UHF antennas. Therefore, use a

strong and rigid mount to safety and securely install the HF/ 50 MHz mobile antenna.

A bumper mount is recommended for stable mounting. However, most recent models of vehicles have plastic

bumpers. For such vehicles, ground the antenna mount to the body chassis with a large wire. Antenna

installation is critical for successful mobile operation. For further information, refer to The Radio Amateur’s

Handbook, Radio Handbook, or other published texts.

GROUND CONNECTION

The ground, which is the other half of the antenna system, is very important when using a mobile whip type

antenna. Connect the feed line ground for the antenna securely to the vehicle’s chassis, and be certain to bond

(electrically connect) the vehicle’s body to chassis. The sheet metal will provide the primary ground plane, so be

sure to establish a good RF connection from the feed line to both the chassis and the body. For comprehensive

information on mobile antennas installations and optimization, refer to the ARRL Handbook or similar publications.

IGNITION NOISE

This transceiver has been equipped with a Noise Blanker and Digital Noise Limiter to filter ignition noises out.

However, some cars may generate excessive ignition noise. If there is excessive noise, use suppressor spark

plugs (with resisters), and/ or DC line filters to reduce the electric noises. The ARRL Handbook, or similar

refereneces, has a wealth of information regarding this topic.

Note:

◆

After installation and wiring are completed, confirm that all work has been done correctly, then connect the DC power cable plug(s) to the

transceiver.

◆

If the fuse blows, disconnect the DC power cable plug(s) from the transceiver immediately, then check all the DC power cables to find the

reasons of the short circuit. The DC cable may be damaged, short circuited, pinched, or squashed. After resolving the problem, replace the

fuse with one of the same type and rating.

◆

Do not remove the fuse holder for any reason.

the cable.

Use a rubber or plastic grommet so that the cable

does not directly touch the vehicle chassis.

DC POWER CABLE CONNECTION

Connect the DC power cable directly to the vehicle’s

battery terminals using the shortest route. Do not use

the cigarette lighter socket! The current rating of the

cigarette lighter socket is too small to operate the

transceiver. Ensure to use a 12 V vehicle battery

which has sufficient current capacity. If the current is

insufficient, the display may darken during

transmission or the trasceiver may work

intermittiently. If you use the transceiver for a long

period when the vehicle battery has not been fully

charged or when the engine has been stopped, the

battery may become discharged in a short time and

will not have sufficient reserves to start the engine.

Avoid using the transceiver under these conditions.

Keep in mind that the TS-480SAT transceiver draws a

peak current of approximately 20.5 A and the

TS-480HX transceiver draws a peak current of

approximately 41A (20.5A + 20.5A) during

transmission.

• Attach the line filter(s) to the DC cable(s) as

shown after the installation (E-type only).

Note:

◆

Do not use two separate batteries to connect each DC cables

from the transceiver (TS-480HX). The DC voltage difference

between DC IN 1 and DC IN 2 connectors at the transceiver must

be within DC 1.0 V to operate the transceiver.

◆

Two supplied DC cables (or two optional PG-20 DC cables) must

be used. Using different length and/ or different gauged cable

could result in a voltage difference between DC IN 1 and DC IN 2

connectors at the transceiver (TS-480HX).
