The Avair AV-40 is a commercial-grade, high-precision radio frequency (RF) diagnostic instrument engineered to monitor transmission line efficiency and forward/reflected power output across VHF and UHF communication networks. Covering an extensive operational frequency spectrum from 140 to 525 MHz, this dual-band Standing Wave Ratio (SWR) and power meter features a selectable 15-Watt or 150-Watt full-scale calibration layout, allowing bench technicians and field installers to handle both low-power handheld portable devices and high-torque mobile transceivers. It stands as an essential physical utility asset for telecommunication service benches, network hardware integration contractors, radio fleet deployment teams, and high-rotation B2B electronics distribution channels.
Built to sustain continuous workshop deployment and rigorous field rotation, the instrument is housed within a rugged, low-profile metallic chassis measuring 85 x 87 x 95 mm and weighing a stable 280 grams to prevent accidental bench slipping during coaxial cable strain. The internal measurement matrix features a nominal 50-Ohm system impedance path terminated in precision-machined heavy-duty SO-239 (PL Female) bulkhead sockets, ensuring absolute electrical continuity, minimized insertion loss, and low-attenuation signal routing down to a 1-Watt minimum detection threshold. Equipped with a clear cross-needle or illuminated analog display powered by an external 12V DC input, the AV-40 provides real-time, highly reliable VSWR monitoring and RF power tracking calibrated to a 10% accuracy margin at full scale.
