ATU-100EXT 1.8MHz~30MHz Mini Automatic Antenna Tuner Element of Amateur Radio Equipment Part of Amplifiers Transceivers

The device is intended for use as an element of amateur radio equipment as part of amplifiers or transceivers or as a separate device that performs the function of matching the output impedance of power amplifiers PA with antenna feeders This device can contain a set of from 5 to 7 inductances and from 5 to 7 capacitors which allows it in the maximum configuration to work effectively in a wide frequency band overlapping radio amateur HF ranges from 1 8 MHz 30 MHz Come on and try it it will not let you down Features The automatic mode of operation provides a particular opportunity for the user to use the device without the need to press buttons and connect any external control the device can be designed without buttons without indication and at the same time will perform its function of matching the resistance of the antenna power supplys line Pressing the Bypass button causes a temporary shutdown of all capacitances and inductances on the paths signal from the input to the output Fa st test mode When power is applied to the device with all three pressed buttons Tune Bypass and Auto the fa st test mode is activated In this mode the device provides power to all relays which allows you to quickly identify faults associated with transistor switches or soldering faults This device can be used in two scenarios as an additional module as part of transceivers or amplifier or as a standalone device in a separate case with or without indication This device can con
