VHF/UHF, multifunction wideband submarine antenna system, 30-3000 MHz

MFA303000S-K

The MFA303000S-K is a multi-function wideband antenna system designed for submarine applications.  The system comprises multiple antennas combined in a single radome controlled by an Antenna Control System (ACS). The system is highly customisable to suit a specific requirement.  Mechanical integration of the system can be tailored to suit the platform.

  • Wide coverage; 30-3000 MHz both Tx (selected bands) and Rx
  • Highly customisable antenna configuration
  • Multi mode; satisfies the need for LoS and Beyond-LoS communication
  • Modular; constructed from proven antenna elements that can be exchanged if other needs arises
  • Compact; high efficiency in a small form factor, given the number of functions/bands

The Multifunctional antenna is highly customisable and the specification below is for the current version.  Please contact Eylex to discuss your specific requirement.
