To develop/manufacture VLF BUOYANT ANTENNA SYSTEM which should be of latest manufacture, conform to the current production standard and should have 100% of the defined life at the time of delivery

Buoyant cable antenna for HF/VLF Reception.

• A VLF/LF/HF buoyant wire antenna system authorizes the deployment and retrieval of a buoyant wire antenna up to the surface where radio signals can be picked up whilst the submarine remains well under periscope depth.
• VLF/LF/HF broadcast reception is possible only with a stable and straight course route according to a keel depth / speed ratio. The Submarine can stay still and quiet and save energy whilst remaining in communication with the shore and/or ships and aircraft at any time; but only in reception.
• VLF system is used for VLF (Very Low Frequency & High frequency) reception. It consists of a towed buoyant wire antenna (diameter: 16-18 mm; length: 625-650 m), which is a single core cable terminated by an electrode and reinforced by a Kevlar structure providing towing resistance.

Future Expectation from the prototype / Technology developed

Successful completion of Land based trials for submarine environment. VLF BUOYANT ANTENNA SYSTEM is intended to be used in Submarine.
