■The controller is designed user friendly, making for easy use. It has NORMAL, 180°, and DIPOLE modes. Because the SWR changes depending on its circumstances, element lengths are adjustable. You can fine tune the SWR at your location. KA-1 controller is equipped with a communication interface for most transceivers in today’s market. To protect your amplifier and VERSA antenna, the controller has a protection circuit that opens the TX Ground line between your amplifier and exciter while the elements are moving. ■Each element has Home Position Sensor so that the controller detects the home position to stop movement. Two separate reels driven by gear belts are used for elements. The reels are installed side by side which brings two major merit for VERSA antenna. One is that it reduces the floating capacitance between elements, and the other is elements move smoothly without stress. ■Versa 403L element length is approximately 50% of full size for 7MHz, 70% for 10MHz, 70% for 14MHz, 88% for 18MHz, and full size for 21MHz and higher.
■Versa 203L element length is approximately 70% of full size for 14MHz, 88% for 18MHz, and full size for 21MHz and higher.

■Models confirmed
      working with VERSA BEAM
■The boom material is MIL standard aluminum, ensuring durability and corrosion resistance qualities. The plate that supports the elements is des igned for maximum durability. To ensure proper element position, silicon rubber and high strength plastic holders are incorporated without adverse effects on higher bands. ■The glassfiber pole supporting moving element is super light that is painted gray to improve durability and weatherproof . Versa 203L uses 3.6m pole.(two sections, 0.7Kg). Versa 403L uses 5.2m pole (three sections, 1Kg). Both poles can be shortened to 2m for transportation.
■Water proof connectors are preinstalled with the junction cable and the control cable, saving time and ensuring proper connectivity. Wiring size and type are designed for this application. The end user needs only to determine cable length required.
