The Avair AV-32CNMNM professional radio frequency duplexer is a commercial-grade, low-loss signal splitting and combining network engineered to enable multi-band transceiver operations over standalone antenna distribution lines. Housed in a heavy-duty, shielded metal chassis to prevent RF cross-coupling and external electromagnetic interference, this premium duplexer isolates frequency paths to protect vulnerable front-end transceiver circuits. It functions as an essential operational procurement element for commercial utility base hubs, emergency dispatch consoles, maritime radio rooms, and high-volume B2B radiocommunication accessory wholesale networks across European markets.
The precision electrical filter matrix of the AV-32CNMNM partitions radio traffic into two highly optimized frequency windows. Port 1 covers the 1.6 MHz to 56 MHz spectrum, encompassing HF, Citizen Band, and low-band 6-meter VHF allocations. Port 2 manages the 140 MHz to 410 MHz band, handling the standard 2-meter VHF band, aviation monitoring bands, PMR/LMR frequencies, and commercial UHF allocations. The rugged main module features a high-integrity chassis-mounted N-Type Female common port connection interface. For rapid, turnkey integration into existing multi-radio benches, the device includes two integrated, flexible coaxial cable pigtail leads: one pre-terminated in a low-loss N-Type Male connector and the other in a standard PL-259 (UHF Male) plug assembly, ensuring instant system alignment and absolute fleet operational readiness.
