Yaesu ATAS-25 Antenna – Portable Multi-Band HF/VHF/UHF Antenna

The Yaesu ATAS-25 is a high-performance portable antenna designed for amateur radio enthusiasts who need a reliable and flexible solution for field operations. Unlike motorized alternatives, it features a manual tuning system, allowing users to adjust the antenna for optimal SWR without purchasing expensive mono-band whip assemblies.

Why Choose the ATAS-25?

• ✅ Manual Tuning for Precision: Easily tune the radiating element of the antenna to achieve a low SWR across supported bands.

• ✅ Multi-Band Capability: Operate on HF, 50MHz, 2m (144MHz), and 70cm (430MHz) — perfect for portable DXing and field days.

• ✅ Tripod Compatible: The ATAS-25 mounts directly to a standard camera tripod, making it an ideal choice for quick, on-the-go deployment.

• ✅ Compact & Lightweight: Weighing just 930g and collapsing to under 2ft, it’s designed for true portability.

• ✅ Tool-Free Setup: Includes radial wires, radiating elements, and an Allen key for fast, simple assembly.

🔔 Note: A duplexer is not included and the ATAS-25 is not recommended for permanent outdoor installation.
