C.4 Tow Cable Considerations
For lightweight tow cables, we recommend that you use tow cables with the
following characteristics:
Type:
Conductors:
Diameter (OD):
Breaking strength:
Working load:
Operational length:
Voltage rating:
Termination:
For armored tow cables, we recommend that you use tow cables with the following
characteristics:
Type:
Conductors:
Diameter (OD):
Breaking strength:
Working load:
Operational length:
Voltage rating:
Termination:
Other important characteristics to consider are that, electrically, the cable must be
50 ohms. The whole cable assembly, deck cable, slip ring, winch, cable and
connectors must be coax all the way from the TPU to the towfish.

NOTE The whole cable assembly must not exceed an attenuation of greater
than 24 dB of insertion loss at 15 MHz. We suggest a working loss of 24 dB
at 15 MHz.
