Momobeam Mono5-10 Monoband Yagi Antennas

Momobeam Mono5-10 Monoband Yagi Antennas are 5‑element OWA (Optimized Wideband Antenna) Yagi antennas designed to deliver low SWR and a stable 50‑ohm impedance across the 28 MHz band, making them a traditional, reliable choice for 10‑meter operation. These antennas are factory‑pre‑calibrated, requiring no additional tuning, and they provide smooth coverage of the entire operating band with excellent front‑to‑back performance, a flat SWR curve under 1.5:1, and impressive gain.

Built on a durable square boom, the MONO5‑10 antennas include an assembly tool along with spare bolts and aluminum tubing, and all components are clearly labeled to ensure quick, straightforward assembly. Mono5-10 antennas can be mast‑mounted or side‑mounted on towers and require a medium‑duty rotator for proper operation.

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.
