Maritime VHF Antenna

156-162 MHz – MADP156-162 (1Y42300)

The MADP156-162 was designed for Maritime Automatic Identification Systems (AIS) and VHF communications applications.

The radiator element is designed for maximum durability and performance. The antenna radiator is sealed in a heavy duty fiberglass radome for mechanical stability and reliability in harsh environments.

Being ground independent, this antenna can be mounted on various maritime platforms (metal or non-metal) with no degradation of performance.



  • Ground independent
  • Single Input
  • Built to MIL-STD-810
