The Avair AV‑20 is a compact, easy‑to‑use SWR and power meter designed for HF and VHF operation. It operates across a 1.8–200 MHz frequency range and measures forward power, reflected power and VSWR for accurate antenna and system checks.

With a 50 Ω impedance, the AV‑20 integrates cleanly into most HF/VHF stations. Two selectable power ranges — 0–15 W and 0–150 W — allow flexible use with QRP, mobile, and higher‑power setups.

The meter sensitivity is 3 W for full‑scale deflection, and the accuracy is rated at 10% full scale, making it suitable for general‑purpose testing and tuning.

Connectivity is via UHF (SO‑239) sockets for straightforward integration with standard RF cables.

Its compact 85 × 87 × 95 mm enclosure makes it ideal for both bench and field use, and its rugged design supports long‑term reliability.

This Rescue Rigs unit is fully working, but has a crack in the casing (cosmetic only). Used items may show typical signs of wear, such as scratches or discolouration.
