Hi. The last time I looked at upgrading my GPS antenna feed line (I'm currently using RG58 style cable) I spent some time looking at the temperature vs propagation delay characteristics of various cables.
I also picked up a spool of cloned "LMR400 style" cable but ended up using that for my amateur radio hobby. If I was going to throw more money at my Time Nuts GPS feed line I'd probably look for a "hard line" style cable with a favourable temperature vs propagation delay characteristic. For a basic installation I expect I would just use RG6 style cable. Good luck.
