Icom AT230 Automatic Tuning System

Manufactured by Moonraker Pty.  Ltd, Australia

AUTOMATIC TUNING SYSTEM

The AT-230 is an automatic tuning system from Moonraker Pty.  Ltd for multi-frequency HF mobile and base station communications.

It is designed to provide push-button microprocessor controlled continuous tuning from 2~30MHz from the IC-F7000, without the use
of an automatic antenna tuner unit.

The AT-230 is a perfect item to complement the IC-F7000 for  communication in environments from the desert to the jungle. Built
tough and the ability to be installed easily to all types of vehicles, your  HF land mobile communication requirements are fully met.

FEATURES:

• Automatic tuning of all frequencies between 2~30MHz
• Tuning is possible while vehicle is moving
• Wide-band HF amplifier built-in to enhance weak reception of weak signals
• Tuning time between channels is 1-2 secs. (Depending on channel separation)
• Rugged construction with all control devices housed in lower section of the antenna
• Top whip element is removable for easy storage or easy parking of the vehicle in a garage

Automatic tuning antenna system for multi-frequency HF radio mobile and base station communications
Designed to provide automatic microprocessor controlled continuous tuning from 2 to 30 MHz from
the transceiver without the use of an antena tuning unit (ATU).

The Moonraker Type AT230 Auto Tune antenna system is comprised of a 2.55m whip
(8.4ft) together with the AT104 antenna control unit (ACU). Typical tuning time for one
channel frequency to another is 1 to 2 seconds with maximum time dependent upon
channel separation.

The system is fully automatic and on installation no further tuning or technician
programming is required. It is robust, reliable and extremely rugged and has passed
extensive testing in off road remote conditions, including tropical jungles and arid
environments, as well as populated areas. The whip may be mounted low down on
the vehicle behind the bull bar, on the bumper bar or even on the tow bar, and
relatively close to the body work on forward control vehicles and buses.

Construction is of anodised aluminium alloy tubing with a sealed lower section
housing the control devices, mid section and stainless steel whip top section, which
may be easily removed to facilitate garaging. Centre loading is utilised for maximum
performance and a wide band HF amplifier, located in the antenna base section and
operated via the ACU, provides enhanced reception of weak signals, particularly
when the receiver is in scan mode.

The ACU, the interface between the antenna and the transceiver, contains the sensor
and controlling electronics. It is compatible with even basic transceiver types that are
able to provide continuous RF for tuning purposes by arranging the ACU to control the
transceiver using a remote PTT line, an external initiate switch and an audible tuning
indicator. Fully automatic operation is possible with more sophisticated transceivers.
It can be installed in any convenient position in the vehicle other than the engine bay
or can be used up to 20m (65.6ft) from the antenna for base station installations.
