ATU-100 ATU100 Machine 1.8-50MHz ATU100mini Automatic Antenna Tuner by N7DDC 7x7 3.2Firmware Programmed OLED

About our ATU-100:

We use the best raw materials. For example, we use T68-2 imported low-heat and low-loss magnetic ring (imported red-brown).
Note: The dark red is a magnetic ring made in China. Buyers please pay attention to distinguish the difference between magnetic rings. C channel capacitors are all 2KV high voltage capacitors. Because we use the best raw materials, we can guarantee that the standing wave ratio will not be very high during use and will be used normally and efficiently during transmission.

(1)The latest firmware version is 3.2：

-SWR greater than 1.1 will automatically activate tuning, and the minimumpower has been changed from 5W to 1W. 3.2 Program can be tuned below 5W.However, Too low value may result in insufficiently fine tuning (originaldefault is greater than 5W auto tuning) , please know this before placing an order.

(2)Parameter Description:

-Power supply range: 10-15 VDC
-Max current: 450mA
-Max working power: 100 watts
-Max measured power: 150 watts
-Minimum power for tuning start: 1 watt
-Recommended maximum power while tuning not above 30 watts. (after tuningyou can set 100 watts and work on this power)
-Minimum measured power: 0.1 watt
-Step for measurement on powers under 10 watts: 0.1 watt
-Step for measurement on powers above 10 watts: 1 watt
-Power measurement accuracy: 10%
-Maximum inductance set: 8.5 uH
-Minimal step for setting inductance: 0.1 uH
-Maximum installed capacity: 1870 pF
-Minimal step for setting capacity: 10 pF

(3)Note:

1.Insufficient tuning may occur within 5W. So do not try to be lower than 5W.

2.Recommended maximum power while tuning not above30 watts. (after tuning you can set 100 watts and work on this power，Otherwise it will burn easily)

3. You need to use 9-12V for the ATU-100 to start. If you use a mobile power supply or a computer USB port to output power, you cannot start the ATU-100 because their voltage is too low.
