AT-100M Pro Antenna Tuner | Power SWR Meter with OLED | Field Tuner for Your Portable Radios

We are proudly to launch a new portable tuner, the AT-100M Pro, which is a upgraded tuner from its precedent AT-100M. Both of the AT-100M and its Pro version are ruggedly built and handy in size, which makes it a fancy field tuner for your QRP or QRO portable radios. The AT-100M Pro tuner is a versatile tuner that will meet most of your working senarioes. Compared to its ancestor, the AT-100M Pro features more groups of L and C combinations, that gives you more chances to tune the SWR down. Nevertherless, it has 60 groups of memories while the AT-100 only has 29 groups.

AT-100M Pro also supports manual tunning, which the AT-100M does not. The tuner features with fast tuning, compact and handy size, and built-in Power SWR meter. The tuner is equipped with an OLED display, not only you can the change 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 have a manual tuning, or to start the automatical tuning with the preset SWR threshold. The new tuner has a morse code mode, by plugging a telegraph key, you are able to practice the morse code on it. 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 15.4cm(L), 1.14″(H) x 2.91″(W) x 6.06″(L), 0.370kg Only
• All New Design, Not directly from the open source atu projects.
• Store up to 60 sets of LC matching combinations.
• Firmware Upgradable, long term support and more new features.
• It’s a Generic Antenna Tuner with Combinations of L and C 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 60 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 Pro: 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.
