[time-nuts] Cabling GPS antennas

I'm installing a Lucent KS-24019L112A connected to a Z3805A with the
two located about 15m apart from each other. Both items connect via a
50Ohm N connector so I'm cabling for that impedance. Ideally I'd like
to buy RG213 or LMR-400 but that is rare'ish down here in NZ and the
price reflects that. I won't consider RG58 as there will be hardly
anything coming out of the end of the cable with the loss it has at
these frequencies. I was thinking outside the square and see that
dual/quad screened RG6 is cheap and plentiful now but of course it's
75Ohm and there would be a big fat impedance mismatch using this. I
thought about looking at fitting impedance matching baluns at each end
but that is not cheap and there are losses involved with this approach
anyway.

Is it just down to bighting the bullet or has anyone had a way round this?

73,
Steve
