About CE

Versions of the AT-130E which display the

“CE” symbol on the serial number seal, comply with the essential requirements of the European Radio and Telecommunication Terminal Directive 1999/5/EC.

FEATURES

Matches all bands

The AT-130/E matches all frequencies on the HF marine band. For example, the tuner matches a 7 m;

23 feet long-wire antenna across 1.6–30 MHz.

Full automatic tuning

Just push the [TUNE] switch on the transceiver, the

AT-130/E immediately tunes for a minimum SWR on any frequency in the HF marine band.

HF operation on any size ship

The AT-130/E allows HF operation where antenna element length is restricted due to space.

Weather resistant

The AT-130/E is housed in a durable, completely weather resistant acrylic case with a rubber gasket.

The antenna tuner can be conveniently installed both on the deck or in the cabin near the antenna element.

Simple installation

Installation is simple. Just connect the control and antenna cables and short-times internal settings. After installation, you never need to open the cover for maintenance.

Preset tuning function

This function provides super fast tuning on your mostused frequency.

45 memories for shorter tuning time

To decrease the tune-up time, the AT-130/E automatically stores the matching conditions for up to 45 frequencies. Retuning for a memorized frequency takes only approximately 1 second.

Super capacitor for memory backup

Even if the AT-130/E is not used for approximately

1 week, the built-in super capacitor backs up the 45 memory contents.

Low power tune up

The AT-130/E emits low output power during tuning.

This feature reduces the possibility of causing interference to other stations.

Emergency tuner circuit

(AT-130E)

To meet with European regulations, the Europe version AT-130E includes an emergency tuner circuit for 2182 kHz operation. If any signal from the control cable indicates an abnormal condition, this circuit is automatically selected.

ANTENNA SYSTEM

n

Antenna for ship

Required antenna element length

Required antenna element length to achieve full performance varies according to the lowest frequency:

The lowest frequency Required antenna element length

1.6 MHz band 7 m; 23.0 feet or longer

4 MHz band 3 m; 9.8 feet or longer

The longer the antenna element, the better the antenna efficiency.

Undesirable antenna element lengths

DO NOT use

an antenna element such as multiples of

1

⁄

For example, if 15 m (49.2 feet) is selected for an antenna element length, you have no problem in the

1.6–25 MHz marine bands range.

Backstay operates as a long-wire antenna.

NOTE: Keep antennas as far away from other objects as possible, especially metal objects.

n

Antenna for land operation

In some countries, HF transceivers can be used for land mobile operation. Ask your Icom Dealer for details, since the radio law varies according to countries.

For land mobile operation on 4 MHz or above, an optional AH-2b antenna element

is available. The

AH-2b includes a sturdy tow hook mount system for holding a 2.5 m (8.2 feet) stainless steel antenna element plus all the necessary hardware.

AH-2b

Refer to the AH-2b instruction manual for the AH-2b and AT-130/E installation to your vehicle. Ask your

Icom Dealer for details.

Connect a suitable antenna element for a coastal station. To achieve full performance, refer to “Required antenna element length” above.

Coaxial cable

Insulate the lead-in cable of the AT-130/E antenna terminal and antenna element from other metal objects.

To prevent interference, keep cables as far as possible from an antenna, electric pump and other electronic equipment.

To prevent erroneous indications, keep cables as far away as possible from the flux gate compass.

Use suitable noise filters for alternators, fluorescent lights, etc. Ask your Dealer for details.

n

Ground and counterpoise

Why a ship’s ground is required

The AT-130/E’s ground terminal

MUST be connected to your ship’s ground. Grounding prevents electric shocks, interference to other equipment and other problems. Grounding also ensures effective signal transmission.

R DANGER! NEVER

connect the ground terminal to the following points. These connections may cause an explosion or electric shocks:

• Gas or electrical pipe

• Fuel tank

• Oil-catch pan

IMPORTANT:

The mounting plate is NOT connected to the AT-130/E’s internal ground. Non-through mast is NOT electrically connected to sea water.

Ideal ground points

One of following points is ideal:

• Ship’s ground terminal

• External ground plate

• External copper screen

Good ground points

If electrically connected to sea water, one of the following points is usable:

• Stainless steel tuna tower

• Stainless steel stanchion

• Through mast

• Through hull

• Metal water tank

Undesirable ground points

These connections may cause noise or electrolysis:

• Engine block

• Keel bolt

Electrolysis

All ground cables from the AT-130/E, HF transceiver, etc. on your ship should be connected to only one ship’s ground.

DO NOT

connect to two or more points. Voltage difference between two or more ship’s grounds may cause electrolysis.

DO NOT

connect between dissimilar metals where an electric current is present. These connections may cause electrolysis.

Counterpoise

If your ship is made of FRP, etc. and a good ship’s ground is not available, connect a counterpoise.

L : Counterpoise length for the operating frequency [m] f : Operating frequency [MHz]

Ground cable

For best results, use the heaviest gauge wire or metal strap available. Make the distance between the AT-

130/E’s ground terminal and ship’s ground as short as possible.

The supplied ground cable can be used for ground connection through a mast. Confirm that the through mast is electrically connected to sea water.

R WARNING!

— When grounding to metal hull

Use a Zinc anode to protect the hull from electrolysis. Ask your technical dealer or installer, or refer to a technical book for RF ground details.
