Momobeam Mono4-10 Monoband Yagi Antennas

Momobeam Mono4 10 Monoband Yagi Antennas are full size, four element antennas engineered to deliver excellent SWR bandwidth, optimal forward gain, and strong front to back performance across the 10 meter band. Despite their robust construction, these antennas remain lightweight, making them easy to handle while still offering the durability needed for harsh weather conditions. Designed for high performance installations, the MONO4 10 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 sturdy square boom, each antenna comes with an assembly tool, spare hardware (bolts and aluminum tubing), and fully labeled components. All hardware bags and aluminum tubes are clearly marked, ensuring quick, accurate, and hassle free assembly. 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. The Mono4-10 requires a medium duty rotator for proper operation.
