Features

  • ATU-100 Automatic Antenna Tuner: The equipment is intended to be used as an accessory of amateur radio equipment, as part of amplifier or transceiver, or as a separate equipment, to realize the function of matching the output impedance of power amplifier (PA) with antenna feeder.
  • 5000mAh Battery This product contains 5000mAh rechargeable batteries. The power input port can be connected to the DC 12V power supply, which is positive inside and negative outside (note: this device contains 15V TVS limiting diode for power supply protection, and the fuse will be blown when the DC power supply voltage exceeds 15V). Before charging, please confirm that the output voltage of the battery charger is less than 5V (the battery charger is not included).
  • Tuning Range Voltage: 10-14.5V DC; Minimum power required to start tuning: 5W; Maximum current consumption: 400mA; Minimum measured power: 0.1W; Maximum working power: 100W; Measurement step of power up to 10 watt hours: 0.1W; Maximum measured power: 150W; Measurement steps for power higher than 10 W: 1W
  • Easy to UseThe hf antenna tuner no need to assemnble and you can use it diretly. This equipment is intended to be used as an accessory of amateur radio equipment, as part of amplifier or transceiver, or as a separate equipment, to realize the function of matching the output impedance of power amplifier (PA) with antenna feeder.
  • Compact and PortableThe dimension of qrp antenna tuner is 9*5.1*2.4 inch. The small size allows you to carry fewer devices and bring more superior connectivity experience. 0.91-inch OLED dual-color display screen is adopted, and the parameters are displayed in four lines: the first line shows the input power value;
  • The second line: display the voltage standing wave ratio; The third and fourth lines display L and C parameter values or antenna output power, efficiency or other key operation status.
  • Quick to Set up Starting Power: in the Manual Mode, the input power of the equipment must reach a certain threshold to trigger automatic impedance adjustment, which is the starting power value. Power Supply: the switch has three levels: Upper: use the power supply line to connect to the DC12V port of the rear panel for power supply. Medium: Turn off the power. Lower: Use internal battery for power supply. (At this time, the battery indicator light is blue, and it is red when charging).
  • Press and hold the RESET/TUNE key, and the word TUNE will appear on the screen. At this time, the continuous power adjustment of the transmitter can be automatically adjusted. Press the RESET/TUNE button for a short time, and the ATU-100 releases the previously adjusted LC relay and is in the straight through position.

Description

Specification: Charging port voltage: 5v (USB) Optimal tuning frequency range: 1.8-30MHz (maximum available frequency 55MHz, transmission loss<8dB Power range: 1-18MHz or SSB/CW, ≤ 100W; 18-30MHz or FM/AM/FT8, ≤ 50W, 30-5MHz pass- through only Allowable power supply voltage range: 10-14.5 V DC Maximum current consumption: 400 mA Maximum working power: 100w Maximum possible measured power: 150W Power measurement accuracy: 10% Minimum installation step of inductance: 0.05uH Minimum capacitance installation steps: 10 pF Minimum power required to start tuning: 5W Minimum possible measured power: 0.1W Measurement step for power up to 10W: 0.1W Measurement step for power higher than 10W: 1W Maximum installed inductance: 8.53uH Maximum installed capacity: 1869 pF Working temperature range: - 20~55 ℃ Manual mode: press and hold the TUNE key to trigger the automatic adjustment of the equipment, so as to match the output impedance of the power amplifier (PA) with the antenna feeder. Automatic mode: no key is required, and the system automatically starts to adjust when it detects that the standing wave ratio is greater than 1:3:1. (This value can be adjusted) This device is in manual operation mode by default. The starting power threshold is 5W, and the screen is always on. At present, the optional functions include 1-5W startup, 10-second screen self- extinguishing/constant lighting, full automatic/manual mode, etc. The parameters used by the product are the main parameters tested by the developer during the software development process, ensuring the reliability of the equipment operation and use in the basic version. Many parameters can be changed by themselves, but they need to be changed carefully to prevent the equipment from being unavailable.

    • This thing is amazing for the price!
Style: 5000mAh Battery
I recently became active again and decided to try FT8. With the crappy winter weather, I was only able to get a random wire (approx. 71 ft.) in the air about 10 feet or so. Feeding it through a 9:1 unun to this tuner, I am able to tune all bands - even 160m! The high bands work better and I have made lots of DX contacts on FT8 with it. ... show more

    • Good little antenna tuner !
Style: No Battery
Review Image by Michael McDonald Michael McDonald
This is probably one of the best antenna tuners for the price. It works on bands 160 - 6 meters, and the customer service was 100%. If you can't find a 12V, 0.5A transformer plug to slice the DC plug to, you would be fine to replace it with another 2.1mm x 5.5mm DC plug. If you do, try to get one with 16-18 gauge wires, which will make it easier if you are hooking up to a power supply. Overall, it works great! ... show more

    • I feel like the power values are displayed like half of the real one in the lower end
Style: 5000mAh Battery
Maybe my unit did not has the software correction in place? I have a FT-100D and I know the power scale by experience, I have checked it against my YS-60 and that against a Bird-43 back in home. I'm on a trip in another country, and buy this unit to use with a EFHW, the reading below ~60W are like half of the ones showed on the rough bar graph in the front of the radio [worst on the 10-20W range] When I get back from my trip I will check that as I don't have a meter at hand here, but otherwise displayed SWR match the ones on the radio, it match 180-6m easily and fast, the battery is good at least for 8hs of run on FT8/WSPR [not tested for longer periods] Good unit beside that issue that is "cosmetic" and do not affect the principal goal: to tune the antenna. Maybe a little tinkering with the Pickit2 in the horizon? ... show more

    • It is rubbish
Style: 5000mAh Battery
I've had the tuner in service for awhile. It's rubbish, it seems to need retuning often on the same frequency. And to top it all off it adds 2 s-units to my noise floor. I've never had a tuner that added toy noise floor ever. The seller wants me send a video or photos of the problem.there isn't anyway to upload a video that large. And how the heck am I supposed to take a picture of that? Do yourself a favor and buy a better tuner than this one. ... show more

This tuner is probably the "best for the money" in it's class! It works well and has exceeded my expectations. I especially like the post in the back to attach a random wire. Lot's of detail on the display about antenna being used too. Coral provide excellent customer service. This tuner is a winner! ... show more

    • Good little auto antenna tuner
Style: No Battery
Review Image by alex yu alex yu
This ATU is fully automatic. I hooked it up to my radio and press the A/M button at the back for full auto tuning and that was it. Every time I changed to a new frequency and key up it will immediately do an auto tune and remember the tune settings. The tuning took about one or two seconds and you can hear the relays clicking inside the ATU. The LCD display shows the forward power, reflected power in numbers and percent and the SWR reading. It was able to tune my radio to 1.04 SWR. It can handle input of 100 watts, my radio does 60 watts but my amplifier does 300 watts so it won’t handle that much power and I returned the ATU not because it is no good but I need an ATU that can handle 300 watts. I highly recommend this ATU for anyone doing under 100 watts and save your headache trying to lengthen or shorten your antenna and changing coaxial cables to lower your SWR. In fact it tuned all 10m, 11m and 12m on the same antenna. My antenna is a vertical dipole using two 102” whips without the 4” springs. ... show more
