Momobeam TRI10 Multiband HF Yagi Antennas are a widely favored, medium‑sized triband Yagi antenna system that delivers impressive performance at an attractive price point. Covering the 20, 15, and 10‑meter bands through a single coaxial feed line, these antennas offer a fully optimized element configuration for each band. On 20 and 15 meters, they feature three full‑size elements—reflector, driver, and director—while the 10‑meter band incorporates four elements arranged as a reflector, driver, and two directors for enhanced gain and directivity.

Engineered for convenience, TRI10 Yagi antennas require no calibration or band‑specific adjustments; during assembly, there is no need to choose between CW and SSB segments. They provide flat SWR below 1.5:1 across all operating bands, making them perfectly suited for modern transceivers and high‑power linear amplifiers.

Each TRI10 is supplied with an assembly tool and spare parts, including bolts and aluminum tubing, ensuring operators have everything needed for smooth installation. The high‑quality 3kW RF choke balun—often an extra‑cost option with other manufacturers—is included as standard to ensure efficient, trouble‑free operation. Built on a robust square boom, these antennas offer long‑term stability, precise element alignment, and a clean, professional appearance. All hardware ships in clearly labeled bags, and every aluminum tube is individually marked, making assembly simple, intuitive, and fast.

Note: Requires a medium load rotator
