Momobeam TRI7-SF Separate Feed 20/15/10 Meter Tri-Band Yagi Antennas are the smallest triband antenna in the Momobeam lineup that features independent feed points. These antennas use full size reflector and driver elements on both 20 and 15 meters, ensuring excellent gain and bandwidth. On 10 meters, they incorporate a three element design—reflector, driver, and director—optimized to deliver strong, reliable performance across the band.
The TRI7 SF series is perfectly suited for multi transceiver stations, offering exceptional versatility thanks to its separate feed architecture. This design allows the antennas to

On 10 meters, they incorporate a three element design—reflector, driver, and director—optimized to deliver strong, reliable performance across the band.
The TRI7 SF series is perfectly suited for multi transceiver stations, offering exceptional versatility thanks to its separate feed architecture. This design allows the antennas to be used simultaneously by three different transceivers, functioning much like three individual monoband antennas when paired with appropriate band pass filters to protect station equipment. As a result, operators can significantly reduce the number of antennas installed on their towers while maintaining full operating capability.
Each TRI7 SF antenna includes a complete accessory set, featuring an assembly tool, spare hardware, and a pair of aluminum replacement tubes. Three high quality 3kW RF choke baluns are also supplied as standard—expensive components that many antenna manufacturers offer only as optional extras. These included baluns help ensure clean, efficient operation across all bands.
Assembly is intentionally simple and intuitive. The antennas use a square boom design, with every piece of hardware packaged in individually labeled bags and all aluminum tubes clearly marked. This thoughtful organization makes installation fast, clear, and error free, even for complex station configurations.
With their separate feed capability, TRI7 SF antennas make it easy for station owners to transition into multi operator contest categories without requiring additional tower space. Key advantages of this solution include a reduced number of installed antennas, lower wind load, elimination of external diplexers or triplexers, and straightforward integration into stacked or multi antenna arrays if desired.
These antennas require three coaxial cables and a medium to light duty rotator. With their combination of versatility, efficiency, and thoughtful engineering, the TRI7 SF Separate Feed Yagi Antennas offer a powerful and space efficient solution for serious Amateur Radio operators.
