Icom AH-730 Antenna Tuner
The Icom AH-730 is a compact, weatherproof automatic antenna tuner for amateur radio operators who need quick, reliable antenna matching across a wide range of frequencies, from 1.8 to 54 MHz—covering 160 to 6 meters—when paired with a wire at least 23 feet long. For those using a shorter wire or whip, it teams up nicely with Icom’s AH-2B mobile antenna to handle 40 to 6 meters instead. The tuner gets its power and control straight from the radio through the included 32.8-foot control cable, so there’s no need for an extra power supply, and it comes with mounting hardware to set it up wherever you need it.
Designed for outdoor use, the AH-730 is rated IPX4 for water resistance, meaning it can handle rain and splashes from any direction without breaking a sweat—just don’t submerge it. It tunes fast, taking about 2–3 seconds to match a new frequency, and it’s smart enough to store 45 memory settings for minimum SWR, so if you revisit a frequency, it’s locked in within a second. During tuning, it only puts out 0.3 W of RF power, keeping interference low and your signal clean. With a power handling of 150 W PEP and 100 W continuous, it’s plenty capable for most barefoot HF setups. Whether you’re running a long wire in the backyard or going portable with the
AH-2B antenna, this tuner’s rugged build and speedy operation make it a solid choice for getting on the air fast, no matter the conditions.
