RF EXCELLENCE: HAMRADIOSHOP IS THE OFFICIAL 4O3A IMPORTER!

We are deeply proud to announce a new era for Italian radio amateurs. HamRadioShop officially becomes the benchmark and importer for the prestigious 4O3A brand. We present the Tuner Genius XL (TGXL) - 2000W, not just a tuner, but an authentic engineering masterpiece that every station dreamed of integrating into their shack.

-- SMART AUTOMATION AND AUTOMATIC BYPASS FUNCTION
Once configured, the Tuner Genius XL will autonomously store individual tuning settings for every minimal frequency change. If the connected antenna is already in a band segment characterized by a good native SWR, the tuner will instantly switch to bypass mode, reducing insertion losses to zero.

-- MILLIMETRIC POWER AND SWR MONITORING
The unit is internally equipped with an extremely precise power and SWR meter, allowing you to monitor the efficiency of your transmission line with millimetric accuracy, providing real-time readings both during active tuning and in bypass mode.

-- HARDCORE RF COMPONENTS UNDER HIGH STRESS
The RF block has been meticulously designed and is built strictly and exclusively with the highest quality RF capacitors, ensuring that the machine is fully capable of withstanding the enormous currents and very high voltages generated in the presence of high SWR. The tuner's C block uses special capacitors capable of individually handling RF currents between 10 and 15 A and operating voltages ranging from 1500 to 3500 V. Careful calculation of all frequencies and impedances has allowed us to choose the best components to make the tuner as efficient as possible on the amateur market. In addition, internal protection mechanisms intervene in extreme cases, reducing maximum operating conditions and shielding RF components from any risk of damage.

• Tuning Modes: Operation managed fully automatically by the hardware or configurable manually by the operator.
• Covered Frequency Range: Continuous coverage from 1.8 to 54 MHz without any interruption.
• Supported Control Interfaces: Native interconnection via Flex LAN, RS232 serial port, Icom CI-V protocol, BCD signals, and Pin-to-Band (PTB).
• Impedance Matching Range: Ability to tune and manage severe antenna line mismatches up to an SWR (Standing Wave Ratio) value of 10:1.
• Hardware Response Times: Complete first tuning cycle estimated between 2 and 12 seconds; lightning-fast relay switching via internal memories in just 20 milliseconds.
• User Display Interface: Large 4.5-inch color touch screen on the front panel for total autonomous management.

• Maximum Nominal RF Power: Continuous delivery supported up to a maximum of 2000 stable Watts with 100% duty cycle in commercial/amateur ICAS mode.
• 1x3 Version Configuration: Antenna matrix management structured with 1 main RF input and 3 dedicated selectable RF outputs.
• SO2R Version Configuration: Advanced management structured with 2 independent RF inputs and 2 dedicated RF outputs (with each single input rigidly matched to its respective output).
• Output Connector Type: Coaxial connectors in UHF standard strictly insulated with PTFE (SO-239A with very high thermal resistance).
• Required Electrical Power: Continuous operating voltage between 12 and 16 V DC.
• Physical Dimensions: Compact chassis with measurements of 30 x 35 x 15 centimeters.
