Momobeam Mono6-20 Monoband Yagi Antennas are engineered for installations focused on high-performance operation on the 20‑meter band. These antennas feature six fully optimized, full size elements that deliver a clean, highly effective radiation pattern and dependable performance across the entire 20‑meter band. Their design ensures a consistently flat SWR below 1.5:1 across the entire band, supporting efficient and stable operation without additional tuning.

Because of their substantial size and the mechanical demands of the Mono6-20, Momobeam incorporates reinforced engineering throughout the structure. The antennas use a robust square‑boom design, offering exceptional rigidity and long‑term durability, even in challenging weather environments.

To simplify assembly, Momobeam includes an installation tool along with spare hardware such as bolts and aluminum tubing. All components are packaged in clearly labeled bags, and each aluminum element is marked for easy identification. This thoughtful packaging approach ensures a smooth and efficient assembly process, even for first‑time installers.

Each antenna comes equipped with a 3kW RF choke to provide proper feedline isolation and help operators achieve clean RF performance right out of the box. Due to their significant wind load and physical mass, the Mono6‑20 antennas require a heavy‑duty rotator capable of handling a large mechanical load for safe and accurate directional control.

Mono6-20 is ideal for serious HF enthusiasts, DX chasers, and contest operators seeking maximum performance and rugged reliability on the 20‑meter band.
