Momobeam Tetra15-DF 40/20/15/10M Dual Feed Yagi Antennas
Momobeam Tetra15 DF 40/20/15/10M Dual Feed Yagi Antennas are multiband HF Yagi antennas engineered with an exceptionally compact design while maintaining high level performance across all four operating bands. On 40 meters, these antennas utilize a Reflector/Driver configuration with element lengths reduced through end loading, a technique originally adopted by W6NL that preserves near full size performance while minimizing overall dimensions. On 20 meters, they employ full-size elements arranged as a reflector, driver, and director, providing strong forward gain and clean directional behavior. For both the 15 meter and 10 meter bands, the antennas incorporate four active elements configured as a reflector, driver, and two directors, ensuring excellent gain and front to back ratios across the higher frequency ranges. Their dual feed architecture allows contest stations to operate on two bands simultaneously, delivering monoband level performance to each operator when paired with appropriate band pass filtering. These antennas include an assembly tool along with spare bolts and aluminum tubing, and they are built on a square boom structure that simplifies the installation process. All hardware is packaged in individually labeled bags, and each aluminum element is clearly marked, enabling fast, intuitive assembly. The system requires two separate coaxial feedlines—one dedicated to the 40 meter band and the other serving the combined 20/15/10 meter array. A medium to heavy duty rotator is recommended for proper operation. Each antenna is supplied with two 3kW RF choke baluns as standard equipment, a notable advantage since many competing manufacturers only offer these components as optional upgrades.

These antennas deliver efficient, optimized performance while maintaining a compact structure, making them ideal for contesting, DXing, and multi station operation. On 40 meters, the Tetra18 DF antennas use a classic Reflector/Driver configuration, with element lengths compacted through end loading. This design approach, originally adopted by W6NL, preserves the on air performance and gain characteristics of a full size 40 meter Yagi while significantly reducing the physical span of the elements. The result is a mechanically manageable 40 meter system that still performs like a full sized antenna. Across 20, 15, and 10 meters, these antennas employ full size elements arranged in proven high gain configurations: four elements on 20 meters, five elements on 15 meters, and seven elements on 10 meters. This design provides excellent forward gain, clean patterns, and wide bandwidth without the compromises of traps, loading coils, or mechanical switching systems. Because no traps, motors, relays, or other moving parts are used, the antennas achieve exceptional long term reliability and mechanical simplicity. All components are built from durable, high quality aluminum to ensure performance and longevity in demanding environments. The dual feed system is a defining feature of the Tetra18 DF antennas. It enables contest stations to operate these antennas as true multi monoband systems. One transceiver/amplifier can operate on 20/15/10 meters, while a second station transmits on 40 meters simultaneously—an arrangement made possible by the fully isolated feed architecture. This configuration maximizes multi operator efficiency, with the only added requirement being the use of external band pass filters (BPFs) to protect equipment between stations. Each Tetra18 DF antenna is supplied with a dedicated Assembly Tool, spare hardware, and two aluminum tube sections to ensure smooth installation and long term maintainability. Additionally, two high quality 3kW RF choke baluns are included as standard equipment—a significant advantage, as many manufacturers treat these essential components as optional add on. Assembly is straightforward thanks to the use of a square boom, clearly labeled aluminum elements, and individually packaged and labeled hardware. These design choices make the construction process intuitive and efficient, even for first time installers. The system requires two coaxial feedlines—one dedicated to the 40 meter feed point and the other feeding 20/15/10 meters —and a heavy duty rotator to accommodate the overall mechanical load. Momobeam Tetra18 DF Dual Feed Yagi Antennas offer outstanding quad band performance, unmatched reliability, and advanced operating flexibility. They are engineered to satisfy contest grade requirements while maintaining ease of installation and long term mechanical stability, making them a standout choice for serious HF stations seeking the highest levels of performance across the 40/20/15/10 meter bands.
