The Avair AV-201 professional SWR and power meter is a commercial-grade RF diagnostics instrument engineered to deliver highly dependable inline monitoring of forward power, reflected power, and Voltage Standing Wave Ratio (VSWR). Designed to integrate seamlessly into high-power base stations and transmission lines, this bench-top console features a wide frequency coverage footprint spanning the 1.8 MHz to 160 MHz spectrum, encompassing all HF bands, the Citizen Band, and professional 2-meter VHF allocations. It functions as an essential operational procurement diagnostic tool for communication test benches, broadcast facilities, regional utility command centers, and high-volume B2B radiocommunication accessory distribution networks across European markets.
The internal electrical engineering of the AV-201 is calibrated for high-power tolerance, featuring a flexible, selectable power measurement matrix ranging from 5 Watts up to a massive 1 Kilowatt (1 KW) peak threshold, with a minimum functional sensitivity down to 0.5 W. The precise cross-needle instrumentation yields factory-calibrated accuracy parameters across multiple stages: 5% at 5W, 7.5% at 20W, 10% at 200W, 12.5% at 400W, and 15% at the 1KW limit. Maintaining a strict 50-Ohm characteristic system impedance, the unit comes outfitted with heavy-duty back-panel SO-239 (PL Female) RF connection ports and runs on a standard 13.8 Vdc source for meter illumination, ensuring immediate installation readiness.
