The KV520-CONTEST (5-element OWA Yagi antenna for the 20-meter band) is a single-band antenna designed for stations demanding maximum performance on 14 MHz. With robust construction, a modern design, and prepared for high-power operation (up to 5 kW), it covers the entire 20-meter band from CW to SSB while maintaining an SWR of less than 1.5:1.

Every aspect of the design was developed with extreme technical rigor: from structural calculations and mechanical resistance to performance optimization through advanced software simulations and modeling. The selection of high-quality materials ensures superior durability, excellent field reliability, and a long lifespan, as well as allowing for future upgrades. All this is validated by practical tests under real operating conditions.

​

Especially suited for DX and Contest stations, the KV520-CONTEST caters to an audience that values ​​precision and performance, where every detail makes a difference in the pursuit of better results, whether to achieve top positions in competitions or to win a significant DXCC.

 

Main features of the KV520-CONTEST:

• 3” square tube gondola with reinforced steel cable truss;

• Central plate with 8mm thick aluminum sheet and U-clamps for fixing to masts up to 2.1/2” inches;
