Engineered to integrate cleanly with 100-watt class HF through 50 MHz transceivers, this external matching unit handles up to 150 Watts PEP input. The \u003cb data-index-in-node=\"318\" data-path-to-node=\"4\"\u003eIcom AH730 HF\/50 MHz (1.8-54MHz) Automatic Antenna Tuner\u003c\/b\u003e allows operators to successfully match standard vertical whips, long-wire configurations, or random-wire elements measuring 7 meters (23 feet) or longer, optimizing total system performance and ensuring a safe voltage standing wave ratio (VSWR) across diverse outdoor setups.\u003c\/p\u003e\n\u003cp\u003eConstructed for permanent outdoor or remote field installations, the unit features a high-strength resin case tested to an IPX4 water-resistant splash protection threshold. This rugged housing protects advanced internal inductive and capacitive matching circuitry from water, heavy weather, and corrosive salt damage. Driven by an intelligent 32-bit microprocessor, the tuner evaluates over 1,040,000 distinct LC combinations to secure a stable match in just 2 to 3 seconds on average. Furthermore, it incorporates 45 non-volatile frequency memories that store tuning profiles to deliver near-instantaneous matching of approximately 1 second when returning to a previously utilized operating frequency.\u003c\/p\u003e\n\u003cp\u003eTo protect neighboring stations and maintain clean spectrum hygiene during setup, the tuner emits a minimal 0.3 Watts of RF output from the antenna during active matching routines. This outdoor tuner is fully controlled and powered directly by the connected transceiver via an included 10-meter shielded control interface cable, eliminating the need for an external standalone DC power cord. Operators should note that the long-wire antenna elements, grounding counterpoises, linear high-power base amplifiers, and primary desktop transceivers are sold separately.\u003c\/p\u003e\n\u003ch3

data-path-to-node=\"18\"\u003eCan this automatic tuner handle the full power of a 500-watt linear amplifier?\u003c\/h4\u003e\n\u003cp\u003eNo, this tuner is specifically engineered for 100W-class base and mobile transceivers with a maximum threshold peak of 150 Watts PEP. High-power amplifiers will destroy the matching matrix.\u003c\/p\u003e\n\u003ch4 data-path-to-node=\"20\"\u003eWhat is the minimum length wire needed to match down to the 1.8 MHz (160m) band?\u003c\/h4\u003e\n\u003cp\u003eTo cover the full 1.8 MHz to 54 MHz frequency range, you must attach a long-wire antenna element measuring at least 7 meters (23 feet) in length.\u003c\/p\u003e\n\u003ch4 data-path-to-node=\"22\"\u003eDoes this tuning system require a separate connection to a ground plane?\u003c\/h4\u003e\n\u003cp\u003eYes, a heavy-duty, clean electrical connection to a proper counterpoise, vehicle chassis, or grounding radial system is absolutely required for safe operational VSWR tracking.\u003c\/p\u003e\n\u003ch4 data-path-to-node=\"24\"\u003eCan I run this tuner without opening up the plastic casing to wire it?\u003c\/h4\u003e\n\u003cp\u003eYes, the advanced layout allows the primary SO239 coaxial feedline and the 4-pin shielded control cables to be connected externally without breaching the weatherized chassis seal.\u003c\/p\u003e\n\u003ch4 data-path-to-node=\"26\"\u003eHow fast does this tuner re-engage when switching between memorized frequencies?\u003c\/h4\u003e\n\u003cp\u003eIf a previously configured frequency path resides within the 45 internal memory slots, the internal microprocessor recalls the LC matrix to execute a match in roughly 1 second.\u003c\/p\u003e\n\u003ch4 data-path-to-node=\"28\"\u003eWill this tuner function correctly if my wire antenna is exactly a half-wave long?\u003c\/h4\u003e\n\u003cp\u003eNo, automatic tuners inherently struggle to match half-wave multi-frequency nodes due to extreme voltage peaks. Avoid cut lengths that align exactly with a half-wavelength.\u003c\/p\u003e\n\u003cp data-path-to-node=\"29\"\u003e \u003c\/p\u003e\n\u003ch3 data-path-to-node=\"30\"\u003eWarranty\u003c\/h3\u003e\n\u003cp data-path-to-node=\"31\"\u003e1-year manufacturer’s warranty.\u003c\/p\u003e","brand":"Icom","offers":[{"title":"Default Title","offer_id":48021769289902,"sku":"AH730","price":569.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0062\/0845\/4744\/files\/AH730a.png?v=1782416466","url":"https:\/\/www.atlanticradiocorp.com\/products\/icom-ah730-hf-50mhz-1-8-54mhz-automatic-antenna-tuner","provider":"Atlantic Radio Communications Corp.
