Momobeam Mono4-20 Monoband Yagi Antennas
Momobeam Mono4-20 Monoband Yagi Antennas are full size, four element Yagi antennas designed to deliver excellent SWR bandwidth, optimal gain, and impressive front to back performance. These antennas remain lightweight for effortless handling while offering the strength needed to withstand harsh weather conditions. MONO4 20 excels in multi stacked array configurations. Stacks can be optimized for maximum forward gain or arranged to broaden directional coverage across multiple regions—making them an excellent choice for contest stations and serious DX operators. Built on a square boom, they are supplied with an assembly tool, spare hardware components, and clearly labeled bolts and aluminum tubes to ensure fast and intuitive assembly. All hardware is packaged in separate, clearly marked bags for added convenience. Mono4-20 can be mounted on a mast or side mounted on towers and require a medium duty rotator. A 3kW RF choke balun is included as standard equipment—an essential component that many manufacturers offer only as an optional upgrade. Momobeam RF Chokes are built using high quality, low loss, double shielded coaxial cable with a Teflon dielectric, combined with carefully selected ferrite material sleeved over the cable. Together, these elements create a high impedance path for RF, providing excellent isolation between the antenna and the coaxial feedline.

Momobeam TRI7-SF Separate Feed 20/15/10 Meter Tri-Band Yagi Antennas
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 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.

Momobeam TRI9-SF Separate Feed 20/15/10 Meter Yagi Antennas
Momobeam TRI9 SF Separate Feed 20/15/10 Meter Yagi Antennas are an ideal solution for operators seeking high performance tri band antennas with independent feed points. Each band is equipped with a full three element configuration—reflector, driver, and director—providing excellent gain, pattern control, and operating efficiency across 20, 15, and 10 meters. These antennas deliver balanced, consistent performance that appeals to both contesters and demanding DX enthusiasts. TRI9 SF antennas are perfectly suited for expanding contest stations and multi operator environments. Their separate feed architecture allows three operators to transmit simultaneously, each using a dedicated band, effectively functioning as if three individual monoband antennas were installed. When paired with appropriate band pass filters to protect equipment, this setup significantly optimizes tower space and reduces the complexity normally associated with multi band installations. This separate feed approach brings several key advantages to station design: fewer antennas are required overall, wind load on the tower is reduced, no external diplexer or triplexer is needed, and multi antenna or multi band stacking becomes simple to configure if desired. The result is a cleaner, more efficient station layout with improved upgrade potential for competitive operating. Each TRI9 SF antenna includes a complete accessory package, featuring an assembly tool and spare parts such as bolts and a pair of aluminum tubes. Three high quality 3kW RF choke baluns are supplied as standard—valuable components that many antenna manufacturers offer only as optional add-ons. Their inclusion ensures excellent feed line isolation and cleaner operating conditions across all three bands. Assembly is straightforward and intuitive. The antennas use a square boom design, and all hardware is organized in individually labeled bags, with each aluminum tube clearly marked for quick identification. This thoughtful packaging makes installation fast, accurate, and stress free, even for operators assembling complex multi antenna systems. TRI9 SF antennas require three coaxial cables and a medium load rotator for proper operation. With their combination of robust engineering, multi transceiver capability, and space efficient design, these antennas offer a powerful solution for serious Amateur Radio operators looking to enhance their contesting capabilities with minimal tower real estate.
