The problem started when I cut the cable in half on accident. It's a
very small coaxial cable.

Question is, can you just solder it back and expect it to work OK?

Is the cable smaller than RG-174?

It looks like RG-174.. Can you get splice kits that small? It is hard
wired to the hummer top magnetic type antenna and the port snap.
(minus my cut)

You can repair that small stuff, just keep it all circularly symmetric and
the ratios of the diameters the same. A more reliable repair would be to
place male and female connectors on the broken ends and rejoin them.

When I fix coax that small I use my Olympus laboratory grade stereo
microscope, Carl Zeiss reducer, Metcal or Pace full soldering/repair system
plus the finest solders and fluxes available. My soldering system costs more
than RB's home theater amplifier, the wire bonding machine and die placer
cost more than any 2 of his cars. Of course his telescope can't compare to
my national standard descending stage geologic microscope. I can sell it as
broken and buy two of his mass produced, consumer level telescopes.

The center conducotrs are very small and that cable is very, very lossy.
Your best bet would be to replace the cable with a larger diameter coax of
the same intrinsic impedance that has 100% shield. Is there a connector at
the antenna? If so, this is easy to do. If you need help, I can suggest a
cable for you. This company may be helpful too:

I find it amusing that RB needs ultra precision audio cables and performance
for acoustic signals at one volt levels and 30 Hz vibrations and yet it is
ok just to solder things together for microwave signals at levels of .000001
volts and 1,500,000,000 Hz vibrations. Amazing. But then you just can't read
about such things in a stereo review magazine or find reviews on the
internet.
