K-697E. Floating (retractable) trailing antenna device

The device is intended for VLF , LF , MF , and HF signals reception on submerged submarines.

The cable array is automatically released from the submerged submarine hull and can be replaced in underwater position.

Received frequency range:

• VLF, LF 6-150 KHz
• MF, HF 0.13-30 MHz

Submarine submergence depth during signals reception:

• VLF, LF reception 100-60 m
• MF, HF reception 85-50 m

Submarine speed during signals reception 2.5-4 kt
Towing speed limit 20 kt
Short-term speed increase up to 25 kt
Cable antenna length 700 m

Operation mode continuous or cyclic

Cable antenna is automatically released from the submarine hull and can be replaced in submerged position
