HamGeek ATU-130C Automatic HF tuner 3.5-54 MHz 250W (PEP)

rating No review at the moment

The HamGeek ATU-130C is an automatic 3.5-54 MHz RF antenna tuner designed to optimise impedance matching between a transceiver or amplifier and the antenna. It automatically adjusts the VSWR to ensure efficient transmission and protect amateur radio equipment.

  • Automatic antenna tuning from 3.5 to 54 MHz
  • Compatible with continuous carrier modes: AM/FM/CW/SSB/RTTY/FT8, etc.
  • Automatic start-up of tuning from 8W, without intervention
  • Intelligent automatic mode: retunes if SWR > 1.3 after frequency change
  • Equipment protection: prevents use at high power if SWR remains high
  • Simple installation: requires only a 10-15V DC power supply
  • Compact design (600g), ideal for fixed station and portable installation

Supplied with: 1 HamGeek ATU-130C antenna tuner, with 1 power cable.

Data sheet

  • Frequency range: 3.5 MHz - 54 MHz
  • Maximum recommended power:
    ≤ 250W in SSB
    ≤ 150W in CW, FM, RTTY
    ≤ 80W in FT8
  • Minimum power to trigger tuning: 8W
  • Supply voltage range: 10-15V DC
  • Power consumption :
  • Typical: 200-300mA
  • Max: 500mA
  • Automatic operation: retune if VSWR varies and exceeds 1.3
  • TUNE mode: manual triggering / reset / LC inversion in test mode
  • Earthing required before use
  • Dimensions:
  • Weight: 0.6 kg

Important note: When using in FT8/FT4 digital mode the maximum power must be ≤80W and when tuning the transmitter power must be at a minimum (10W max), otherwise the tuner will burn out and this will not be taken into account under the warranty.

Instructions for use :

Before use, the antenna tuner must be correctly earthed. Connect the RF input of the tuner to the RF output of the HF radio using an RF cable (not included).

Connect the RF output of the tuner (it is recommended to install the antenna at a height of 3 to 6 metres above the ground and to use a wire 7 to 22 metres long with a cross-section of at least 4 mm².

For installations at higher altitudes, it is advisable to take lightning protection measures, such as installing lightning conductors).

- Connect the tuner's power supply (12-15V), usually shared with the HF radio.
- Switch on the HF radio and tuner. The unit will perform a self-test and display its status.
- Tune the HF radio to the desired frequency. Set the operating mode to AM, FM, CW, FT8, RTTY or any other mode that provides a continuous carrier signal.

Press the transmit or CW button on the radio to start transmission at a maximum power of 8-15 W. At this point, the HamGeek tuner will begin to tune itself automatically.

When the Standing Wave Ratio (SWR) drops below 1.5, the tuner will automatically stop tuning. You should then stop transmission. At this point, on the current frequency, you should switch the HF radio to the desired operating mode, after which it will be able to transmit at high power.

When changing frequency bands, the tuning process must be repeated.

If the tuner fails to achieve an SWR of less than 1.5, press the TUNE button to reset it and repeat the antenna tuning process. If tuning still fails, the impedance of the antenna feed system may exceed the tuner's range, or the earthing should be checked.

If the tuner does not initiate tuning, check the following points:
- All cable connections are secure.
- The tuner is set to automatic mode.
- The radio is set to a mode that provides a continuous carrier, not SSB mode.
- The transmit power is sufficient to initiate tuning (it should be greater than 8W but not more than 20W).
