Sirio Monsoon 10m Antenna

Experience stronger, clearer communication with the Sirio Monsoon — a 5/8-wave ground-plane antenna built specifically for the 26–30 MHz range. Designed to deliver reliable long-distance performance, it offers impressive gain, excellent bandwidth stability, and outstanding signal penetration.
With its ability to handle high power levels, the Monsoon becomes a perfect companion for operators who want their voice to reach further with confidence. Whether you're chasing DX across the globe or maintaining local network reliability, this antenna ensures your signal rises above the noise with authority.

 

Sturdy Construction & Convenient Bottom-Tuning

Engineered for long-term outdoor use, the Monsoon combines durable aluminium, weather-resistant components, and a tall profile that naturally promotes low-angle radiation — ideal for long-range contacts.
Its standout feature is the bottom-tuning system, which allows for precise frequency adjustment easily.
From the reinforced coil to the robust mast sections, every part is built to survive harsh weather, making this antenna a reliable choice for operators wanting performance without constant maintenance.
