Resistive splitters are relatively easy to make, but in all honesty,
there's no reason why you shouldn't just use a UHF/VHF antenna splitter,
the resistive ones work over several orders of magnitude of frequencies.
It will cost less than you can buy the parts for.


IIRC, cars use 300 ohm aerial systems - domestic 75 ohm. So splitters
would be slightly different for maximum efficiency.


I have never come across 300 Ohm ribbon cable in a car, so I would tend
to think that the coax for a car radio would be close to 50 Ohms.

No - the "coax" on a car aerial is special "low capacitance" cable,
and is indeed about 300 ohms.
