OptiBeam OB5-6: Discover the Thrills of the "Magic Band" with a World-Class 6-meter Yagi!

Take your amateur radio experience to the next level with the OptiBeam OB5-6—a premium 5-element monoband Optimized Wideband Array (OWA) Yagi antenna engineered for operators who demand maximum performance and reliability on the 50 MHz band.

Why Choose the OB5-6?

• Exceptional Gain & Directivity

  Achieve a forward gain of 9.1 dBd: up to 16.7 dBi at 20 ft. (6m) above ground, and an impressive 22 dB front-to-back ratio, ensuring strong signals and minimal interference.

• Ultra-Low SWR for Maximum Efficiency

  Enjoy a near-perfect match with 1.0:1 to 1.1:1 SWR across 50.0–50.3 MHz, guaranteeing efficient power transfer and superior performance.

Smart, Durable Design

• Compact Yet Powerful

  With a 14.57 ft. (4.44 m) boom and 9.0 ft. (2.75 m) turning radius, the OB5-6 delivers excellent performance in a very manageable size.

• Built to Last

  Rated for 80 mph (130 km/h) winds, with a rugged structure weighing just 19.84 lbs. (9 kg) and a surface area of 2.26 sq. ft. (0.21 sq. m) —perfect for challenging weather conditions.

• Easy Installation

  Use a single 50-ohm coax to the included 1:1 choke balun for a straightforward project .

The OptiBeam OB5-6 is a high-performance beam antenna engineered to deliver strong, clear signals and reliable operation on the 6-meter band. Whether pursuing DX contacts or competing in contests, its advanced, compact and rugged design provides pure performance for effective communication with confidence.

The OptiBeam OB5-6 is a durable five-element OWA Yagi designed for stable, directional 50 MHz performance in fixed amateur-radio installations. This efficient 6-meter monoband Yagi was computer-optimized and refined through extensive real-world testing for stable performance across the design range.

The 0.73 wavelength boom carries one reflector, one driven element, and three directors. Its OWA spacing—one director close to the driven element and two farther apart—supports high gain, a strong front-to-back ratio, and consistent performance across the usable band.

Exceptionally low SWR across the frequency range supports efficient power transfer and reduces retuning with modern transceivers and amplifiers. A stable radiation pattern also provides predictable directivity as 6-meter propagation changes.

Built for permanent installations, the OB5-6 emphasizes strength and weather resistance while balancing durability with the support needs of a five-element 6-meter array.

For DX, sporadic-E openings, or contesting, the OB5-6 offers substantially greater directivity than simple wire or vertical antennas. Its efficient OWA design and robust construction make it a durable solution for demanding 50 MHz operation.
