Kohjinsha KA1-403SL
40m-6m Dynamic Antenna

Versa 402Lite / 403Lite / 404Lite antennas are designed to provide excellent performance with a significantly reduced physical size. Compared to a full-size Yagi, they are approximately 50% shorter on the 7 MHz band, about 30% shorter on the 10 MHz, 14 MHz and 18 MHz bands, making them ideal for installations with limited space while maintaining high efficiency.
On the lower bands they operate as VP (Virtual Phased) Yagi antennas, with an effective length reduction of around 12% (models 203Lite, 204Lite, 403Lite, 404Lite), ensuring good gain and front-to-back ratio. Above the 21 MHz band, the antennas perform as full-size Yagis, delivering maximum performance. The 402Lite features 2 elements, the 403Lite3 elements, and the 404Lite 4 elements, allowing operators to choose the best compromise between size, gain and directivity.
