AT-100M Automatic Antenna Tuner | Power SWR Meter with OLED | An Compact and Handy Antenna Tuner for Field Operation

A good antenna tuner is a must have gear for ham radio hobby. Some times, we want our tuner not only to work at home base station, but also work at field. The AT-100M tuner is a versatile tuner that will meet most of your working senarioes. For most of antennas, the L and C combinations of AT-100M will tune the SWR down in most cases. The tuner features with fast tuning, compact and handy size, and built-in Power SWR meter. Equipped with an OLED display, not only you can the tuning parameters, but also monitor the real-time Power and SWR values. The tuning process could be either in a manual way or an automatic way, you can press the TUNE button on the front panel to start the tuning, or automatically start to tune with the preset SWR threshold. An ideal tuner will not seat at your radio desktop of your home always, and with its handy size and built-in battery, it could be brought out for field day activities.

Highlights:

• Built-in SWR and Power meter, cost effective and high performance
• Build with Quality Parts: RF Toroids, 1N5711 as the RF detector
• Compact and Handy Size: Only 2.9cm(H) x 7.4cm(W) x 13.9cm(L), 1.14″(H) x 2.91″(W) x 5.48″(L), 0.370kg Only
• All New Design, New Code, Not directly from the open source atu projects.
• Store up to 20 sets of LC matching combinations.
• Firmware Upgradable, long term support and more new features.
• It’s a Generic Antenna Tuner with Combinations of L Match that works for all radios and antennas, no Control Cables needed.
• Works as a Power SWR meter (SWR, FWD, REF) for antenna measurements if you bypass the tuner.
• Fast Tuning: It picks up the internal 29 groups of tuning combinations for the quick tune if it is not an initial tuning.
• For QRP or 100W Scenarios.
• OLED Display: All Tuning Parameters are showed on the 0.91″ OLED, including SWR, RF Power, SWR Curve, Power Curve, Relay and Battery Voltage Status.
• Advanced Settings Accessible: For some high level users, some configurations like tuning storage settings, tuning speed, initial power for tuning, SWR threshold, SWR and Power Calibration, signal test, and relay test etc… are accessible.
• Built-in Lithium Battery: No additional DC power supply needed when working, a USB Type-C is reserved for battery charing. With a Battery Inside, it is ideal for QRP or Field Operation.
• Built-in Buzzer: A buzzer is integrated for beeping while it is in tuning progress or in HIGH SWR status. When the SWR value is over the threshold value, the buzzer will be active to warn.

Note: For All Antenna Tuners including AT-100M: In order to protect your transceiver and tuner, do not forget to reduce your transceiver’s power output to its minimum value(100w to 5w, QRP radios to 1W) before starting a tuning process.

Operating Instructions:

1. Make sure your tuning frequency is within the tuner’s working frequency.
2. Connect your radio to the tuner’s IN port, and antenna to the tuner’s OUT port.
3. Set your radio to its lowest power output, like 5W for 100W radios and set your radio mode to CW or FM or AM mode.
4. Apply a long press to the TUNE button.
5. Key your radio to start transmitting RF power out to your tuner. The tuner will automatic to start switching the relays and find out the best LC combinations for the best SWR.
6. The OLED tells the tuned SWR value and the tuning process ends;
7. Set your radio’s RF power and mode to your desired ones and start to CQ.
