Hi guys Id like to ask about getting a signal down more then 6' in fresh water. It must be possible to get a signal down if they are able to do transmitter signals at deep depths? Has anyone messed with or know how to get an RC to work say at 30-40'??? If i ever get this heavy tin Can done id like to take it deep with a cam?? Ive even thought of hard wireing it like an ROV Doc

Maybe like this?
Hi
I've been cooking on this idea, which I copied from my web:
I) "Towed sonar" antenna:
As you know, the radio range is not all that great in water, and often limits the diving depth to only a fraction of what the design could otherwise endure. To solve this issue, I came up with this idea:
Real subs have a towed sonar that is used to cover the otherwise deaf angles behind the sub's own propeller noise. The towed sonar is basically a microphone, dragged in a long cable way behind the sub. If you build a "towed sonar", and drag it behind the sub in a long wire, and then construct the sonar to ride in the surface, then you can place your antenna in this surface-towed sonar, GREATLY improving max. diving depth. The towed sonar could be constructed so that it can be detached if not used, as the cable will take up too much space within the hull. The only danger is that the cable might get entangled in something (or somebody) during a run.
I chose not to build this feature in the initial stage, but have reserved space for this feature. -
Re: Radio Signals
These subs routinely dive to 20-30 ft and possibly more. Propulsion is from bilge pumps which are apparently sealed very well. Electrics are well sealed with only wire protruding. TV signal I think is limited to above water, though.Hi guys Id like to ask about getting a signal down more then 6' in fresh water.
