マルチバンド・YAGIアンテナKA1-206
Versa 402Lite / 403Lite / 404Lite is about 50% shorter in the 7MHz band, about 30% shorter in the 10MHz band, about 30% shorter in the
14MHz band, and about 30% shorter in the 18MHz band.Operates as a VP Yagi antenna with a 12% reduction (203Lite, 204Lite, 403Lite,
404Lite), and as a full-size Yagi antenna above the 21MHz band.(402Lite is 2 elements, 403Lite is 3 elements, 404Lite is 4 elements).
Versa 203Lite / 204Lite is shortened by about 30% in the 14MHz band and about 12% in the 18MHz band.It operates as a shortened VP
Yagi antenna and as a full-size Yagi antenna (203Lite is 3 elements / 204Lite is 4 elements) above the 21MHz band.(203 Lite is 3
elements / 204 Lite is 4 elements) 403S Lite is a 2-element VP antenna that is shortened by about 50% in the 7MHz band and about 30%
in the 10MHz band.Also, the 14MHz band and above operate as a full-size 3-element Yagi antenna. Both Versa Lite series support each
frequency band Switching the loading coil with two sets of relays, 7 to 50MHz (402Lite / 403SLite / 403Lite / 404Lite) or 14 to 50MHz
(203Lite / 204Lite) Fully covers up to and demonstrates performance approaching full size. Of course, like the standard version and Super
Versa, the frequency from the radio Since the tracking is automatically performed, the range of good SWR, which is the fate of the
shortened antenna, is never narrow, and the frequency is always in operation.The SWR is kept optimal (1.0-1.2 or less). Recommended
for those who have been hesitant to install Versa due to the difficulty of constructing a large antenna. It is a good antenna.
■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.

■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.

KA1-DP 7〜50MHz Dipole
The radiator section of the popular KA1-Lite series has been added to the lineup as a dipole. The controller has been newly designed exclusively for KA1-DP. Since the element length can be changed continuously from 7 to 50 MHz, it can be used not only for mobile operation but also for fixed stations. You can also play an active part as a tena. As with other VERSA series, control the antenna (element length) from a transceiver or personal computer. Since it can be rolled, there is nothing to bother with during QSY. KA1-DP is shortened by about 50% in the 7MHz band and shortened by about 30% in the 10MHz band. As a result, it operates as a full-size dipole in the 14MHz band and above. In the 7MHz band and 10MHz band, two sets of loading coils are switched by a relay to shorten the time. I have realized Ipol.
