Cyrus Mazzoni ATU 2.0 unit will control you for antenna loop Baby Midi Stealth
They're made of aluminum. Even the smallest has an elemonto of 50 mm in diameter ( 2 inch). Because of the 'wide area' they have less loss of gain. Both end sections are welded to the connector, thus avoiding contact resistance.
The tuning capacitor is not a simple variable but a 'large' capacitor with aluminum slats in the air. Both armors are welded directly to the loop and resistant to high powers! The distance between the armor, in the smallest antenna, is 14mm (about 1/2 inch).
A waterproof actuator opens and closes the armor allowing it to be tuned (SWR tuning).
Auto Control Unit
The auto-control unit has installed an agreement circuit and is implemented by a small keyboard: type the operating frequency, wait a few seconds for the automatic agreement and you are ready. No attempt, no hesitation, there is no need to check the rosmetro. The selected frequency and the resulting ROS are displayed on the LCD display. The maximum power that can be used with the automatic control unit is 250 W !
