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 50 

antenna of good quality, a high-quality 50  coaxial

cable, and top-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

with consumer products such as stereo receivers

and televisions. You may even cause interference

with your own transceiver. Reports that your signal is

distorted could indicate that your antenna system is

not efﬁ ciently radiating your 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. Refer to page 9 for the

location of the antenna connectors.

The LF band is outputted only from the DRV terminal.

Note:

◆ Transmitting without connecting an antenna or other

matched load may damage the transceiver. Always connect

the antenna to the transceiver before transmitting.

◆ All ﬁ xed stations should be equipped with a lightning arrester

to reduce the risk of ﬁ re, electric shock, and transceiver

damage.

◆ The transceiver’s protection circuit will activate when the

SWR is greater than 1.5:1; however, do not rely on protection

to compensate for a poorly functioning antenna system.

GROUND CONNECTION

At a minimum, a good DC ground is required to

prevent such dangers as electric shock. For superior

communications, 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 is always a chance that a storm will

occur 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 additional protection.

DC POWER SUPPLY CONNECTION

In order to use this transceiver, you need a separate

13.8 V DC power supply that must be purchased

separately. Do not directly connect the transceiver

to an AC outlet. Use the supplied DC power cable to

connect the transceiver to a regulated power supply.

Do not substitute a cable with smaller gauge wires.

The current capacity of the power supply must be

20.5 A peak or more.

First, connect the DC power cable to the regulated DC

power supply; the red lead to the positive terminal and

the black lead to the negative terminal. Next, connect

the DC power cable to the transceiver’s DC power

connector.

• Press the connectors ﬁ rmly until the locking tab

clicks.

Note:

◆ Before connecting the DC power supply to the transceiver,

be sure to switch OFF the DC power supply and transceiver.

◆ Do not plug the DC power supply into an AC outlet until you

make all connections.
