OptiBeam OB4-40 4 Element 40m Duo Driven Monoband Yagi

The OptiBeam OB4-40 is the best dual-driven 4 element 40 meter monoband Yagi in the world. It features:

• OptiBeam's nearly loss-free high-Q air coils which reduce the length of the elements to less than 15 meters (49 ft.)

• Complete coverage of the 300 kHz of the 40 meter band with excellent SWR, constant gain and a stable radiation pattern

• OptiBeam's exclusive 40 meter decoupling stubs which eliminate interaction with other nearby Yagi antennas in the frequency range of 14 to 30 MHz

OptiBeam's antenna technology has achieved directional antennas with extraordinary electrical properties, including the highest efficiency, optimum band coverage, constant gain, and virtually unchanging patterns across the band, with low SWR. These antennas maintain consistent electrical characteristics under all weather-conditions and include a high power balun with UHF female connector for your 50-ohm coaxial cable.

OptiBeam Antennas are distinguished by their advanced mechanical qualities. Specially configured, stable, and properly shaped element holders, robust square and round booms with effective and solidly built element transitions are hallmarks of OptiBeam quality. They provide advanced physical properties, including proper balance and high stability over the entire system. Elements are perfectly aligned and secured against torsion with minimal sag for a visually pleasing appearance.

OptiBeam antennas are made for those who understand the true value of investing in proven electrical performance and unequalled mechanical quality for the ultimate in reliability. They are built to withstand the harshest conditions using the absolute best materials, including high quality aluminum alloys, UV stable synthetic parts, and stainless steel hardware. OptiBeam antennas are designed to be easier to build than others, often arriving in subassemblies with every part carefully sorted, clearly labeled, and extremely well packed for worry-free shipment and straightforward installation.

For enthusiastic operators of all pursuits, OptiBeam provides the advantage of pure performance. Proven in the field and confirmed by the most demanding hams around the world — OptiBeam is the perfect choice for your station.
