RG-58 is very lossy at GPS signal frequencies.

The sweet spot on the cost/performance chart is RG-6.  It's widely available 
as low loss cable TV.  It's slightly larger diameter than RG-59.  It's 75 
ohms, but the loss due to mismatch is small relative to the cable loss.

These are my opinions.  I hate spam.
