The Diamond MR77S is a premium commercial-grade, dual-band mobile transceiver antenna engineered to deliver stable omnidirectional voice and data communications for automotive fleets, field service vehicles, and portable radio stations. Measuring exactly 50 cm in length and weighing a lightweight 400 grams, this compact vertical whip antenna operates seamlessly across the VHF (144 MHz) and UHF (430 MHz) frequency bands. It stands as an excellent plug-and-play hardware utility asset for outfitting transportation operations, emergency response services, and security vehicles that require low-profile, rapid-deployment communication lines.
Built for dependable field reliability, the MR77S features a high-flexibility metallic radiator rod integrated with a specialized open center-loading coil designed to maximize radiation efficiency. The antenna structure is permanently attached to a rugged, heavy-duty black magnetic base that ensures solid mechanical retention on any flat metallic vehicle surface without requiring drilling or permanent physical installation. Outfitted with a pre-installed 4-meter RG58U coaxial distribution cable, the assembly is pre-terminated with a high-retention SMA male connector, making it immediately ready for direct integration into standard handheld transceivers or compact mobile radio decks.
