D2241-M2G Shipboard Antenna
The D2241-M2G Shipboard Antenna is a rugged, dual-band shipboard antenna with VHF (108–174 MHz) and UHF (225–400 MHz) outputs, delivering 360° omnidirectional coverage and high-isolation performance for secure naval, coast guard, and maritime defense communications.
Description
The D2241-M2G Shipboard Antenna is a rugged, high-performance design for essential ship-to-ship and ship-to-air communications in naval, coast guard, and defense operations. It features two independent connectors: one for VHF output operating in the 108-174 MHz frequency band and another for UHF output covering 225-400 MHz. This allows for simultaneous dual-frequency operation with high isolation and minimal interference.
Engineered for 360-degree omnidirectional coverage, the D2241-M2G ensures uninterrupted long-range communication, optimizing signal clarity and reliability for naval fleets, coastal command centers, and maritime defense networks. Its high-isolation design enhances secure connectivity between vessels, aircraft, and ground-based command units.
Built to military-grade durability standards, the D2241-M2G can withstand harsh maritime conditions, including exposure to saltwater, high winds, and extreme weather, ensuring long-term operational reliability for critical shipboard communication networks.
