I actually called Rena (USA) on this a few years ago, and they said that
they don't make the cable except when there's a need for a large enough
order, and there just wasn't the demand for it, so I couldn't buy one, at
least in the US.  Maybe the guy I talked with was just an idiot, or maybe
things have changed now.  That would be nice.

One small caveat is that such cables are in fact 120 volt units, and
having high voltage drops ACROSS your tank is a potential disaster if the
insulation should wear thin at opposite ends of the tank.
