 Model WD-118-400 118-400 MHz 2.15 dBi Gain 
 

NAVAL SHIPBOARD ANTENNA

Design Features: WD-118-400 VHF UHF aviation band heavy duty fully welded discone antenna is specially designed to survive the most extreme conditions, where conventional antennas often fail. Due to its low VSWR through entire band from 118-400 MHz., this discone antenna can be used as a transmitting and receiving antenna with high efficiency, to meet the broadband requirement of a base station antenna such as spectrum monitoring or jamming application without need of multiple antennas. WD-118-400 wideband discone antenna is extremely rugged, fully welded at all junctions, all weather model, does not require any field tuning or adjustments. The wide vertical beam-width of discone antennas allows clear communication for ground, sea, and ground-to-air applications. The fully welded wide band discone antenna is highly suitable for Oceanic application especially in arctic region where vibration and ice loading are main concern.

Constructions: The fully welded wide band discone antenna uses 6063T6 Mil grade ultra corrosion resistant architectural anodized aluminum alloy with powder coating finish to protect the antenna further from severe environmental condition. All internal junctions are enclosed within a ruggedized radome to ensure survivability in the worst environments. The powder coating on all metal surfaces ensures complete protection from corrosive gases, ultraviolet radiation, salt spray, acid rain and sand storms in desert environments. Discone Antenna termination enclosed inside the mounting pipe for complete weather protection. All the screws, nuts and bolts of heavy duty wide band discone antenna are made of type 316 marine grade stainless steel.
