Instruments

Fitted the underwater radio to the brackets I had made ages ago.  The arial\antenna\transducer (not sure what you call it) needs to pass through the hull via the sub conn bulkhead connector.  The cable has 3 pins on the plug where it connects to the instrument, so I was expecting there to be 3 seperate wires inside.  When I cut it, I found its actually a coaxial cable.  I didn’t expect this although I suppose I should have made a bit more effort to find out.  Anyway, I have wired it together through the connector with the shielding and inner cable connected to the through hull, but I don’t hold out much hope for it working.  I did wire my TV arial up like this years ago and it was fine, so you never know, but I am almost sure this will need to be re-done.

I shortened the cable so there was a bit left to show the method of splitting the 2 wires.  Black wire bottom of picture.

I will rig up the other end and then test it in a bucket with the reciever.
