6-8 m, HF transmitting, MF-HF receiving antennas

Modular Antennas

High quality, high-performance fibreglass rod antennas Transmitting antennas for simplex and duplex SSB receiving antennas for MF-HF and SSB.

  • The modular MF-HF antenna system is our answer to the Global Maritime Distress and Safety System (GMDSS).
  • The antennas can be used as part of any MF/HF communication system but are specially designed to satisfy the demands of the GMDSS.
  • Depending on the equipment and the traffic pattern of the vessel you can choose between antennas of 6, 7 or 8 m length.
  • Different installations demand different mounting solutions. The modular system provides you with all the solutions you need:
    • Installation on a mast, tube or directly to a bulkhead wall.
    • Installation onto welded brackets.
    • Flange or deck mounting with side feed.
    • Flange or deck mounting with end feed.
    • Flange mounted versions with side feed can be fitted with a manual or electrical tilting bracket.
  • The antennas can be equipped with connecting kit for transmitting/transceivers (AT-Kit) or a kit for receiving (AR-Kit). The receiving kit can be supplied with a matching transformer (AR/T-Kit).
  • Receiving antennas can be supplied with protection against static discharges that can harm the receiver.
