LOOKING FOR COMMS ADVICE
First question guys, so, here we go!! I'm at early stages of building an ROV, well design stage actually.Mechanical design is almost there, but, control is the problem.I'm looking to launch from my boat, at sea to a depth possibly 40-50 ft.Can I use radio control (40mhz) with a tether as an antenna (onboard battery but, tether also carries supply voltage to lights) or do I use wired method (joystick/onboard relay set-up).Both seem to bring problems, rc and seawater don't like each other and the volts drop thru cable distance for the wired method.Thanks in advance for any help.Cheers Brian.

Re: LOOKING FOR COMMS ADVICE
Hello,
Well I am trying to figure out kinda the same think using rc receivers and transmitters.My idea is to have on board batterys and make the whole rov radio controlled and completely wireless ( no tether). I would have the rc antenna on the rov be long enough to be on attached to a floating buoy on the surface. I belive this would provide a direct radio control circuit to the rc receiver.
I hope this helps!

Rf will not travel well enough through water to control the ROV. I have heard of people using a tether From the antenna connection to the RX on the ROV.

Thanks for the advice, I guess I will still have to use some sort of tether for the control signals for my ROV.
