what do you use as umbilical cable to your ROV?

what type of cable do you use as umbilical for your ROV?

i've been looking at some pvc hybrid cable with 1x coax(video), 2x0.14mm2 (com) and 3x1mm2(pwr) but the downside is a price of 15$ per meter!(approx 5$ pr feet) and its quite heavy.

i would really like a neutral buoyancy cable in a lower price range.

i'm using it with the rov-asia boards.

Two-Wire Tether

I use an off-the-shelf data over power-line system. This allows for data transfer and also powers the ROV, but is about as thick as two strands of fishing line. Also very inexpensive. Here's the configuration.

Hi Eric,

Have you thought about running a ground wire to the ROV itself as your circuit looks like it relies on the water to make a circuit which for sea water is still quite a high impedance and fresh water is very high.

Normally we tie a wire to the chassis of the ROV from our GFD modules, to basically anything metal that can zap you

i'm also thinking about using high voltage and downconverting in the rov.
i would need a total of 4 wires for power and communication(2 for power and 2 for coms), the boards i use have a own communication protocol on a 2-wire line that can be run up to 500 feet.
i would also need a usb or video to power-over-ethernet converter like used on the link.
