Icom AH730 Automatic Antenna Tuner 1.8-54 MHz HF/6m Amateur Radio

The Icom AH730 is a high-performance automatic antenna tuner designed for amateur radio operators who need fast, reliable antenna matching across all HF bands plus 6 meters. This high-speed, automatic antenna tuner is designed to quickly match a long wire or whip antenna from the 160m (1.8 MHz) band through the 6m (54 MHz) band. Rated for 150W (PEP), this IPX4 water-resistant tuner features 45 memory channels for instant recall, making it ideal for multi-band remote operation with Icom transceivers like the IC-7300MK2 and IC-7610.

Key Features:

• Wide Frequency Coverage: Tunes 1.8 MHz (160m) through 54 MHz (6m) with a 7-meter (23 ft) or longer antenna element.
• High-Speed Tuning: Quick automatic tuning, achieving a match in 2–3 seconds on average, and approximately 1 second from memory recall.
• High Power Rating: Handles up to 150W PEP (100W Continuous), suitable for most 100W-class transceivers.
• It has 45 memories to store the minimum SWR settings.
• Low Power Tune-Up: Emits only a minimal 0.3 W of RF output during the tuning process, minimizing interference to other stations.
• IPX4 Water Resistant: The rugged high-strength resin case protects the internal components from water splash, weather, and salt damage, ensuring reliable outdoor operation.
• Coaxial and control cable connections are now on the exterior of the box, eliminating the need to open the case.

Technical Specifications:

• Frequency Range: 1.8-54 MHz (160m-6m amateur bands)
• Maximum Input Power: 150W PEP, 100W continuous
• Tuning Accuracy: VSWR 2.0:1 or less
• Input Impedance: 50 ohms (SO-239 connector)
• Power Supply: 13.8V DC ±15% (supplied via control cable from transceiver)
• Current Consumption: Less than 0.7A
• Operating Temperature: -10°C to +60°C (14°F to 140°F)

What's Included:

• AH730 Automatic Antenna Tuner
• Control cable (10 m, 32.8 ft, OPC-1465)
• Mounting kit (U-bolts and plate)
• Weatherproof cap

The ICOM AH-730 automatically tunes any long-wire antenna that measures 23 feet or longer with a suitable ground plane for portable or mobile operation on the 160–6 Meters Amateur Radio bands. Directly compatible with many Icom transceivers, including the IC-7300MK2, IC-7610, and IC-7100, which supply the necessary 13.8V DC control voltage. The built-in 32 bit microprocessor chooses the lowest SWR using more than 1,040,000 different LC (coil/capacitor) combinations.
