Hi RG-6 Quad Shield should be fine as long as it’s meeting the published specs. The advantage of LRM-400 is that you likely *know* where it came from and what the specs are.
If you decide to split the antenna between GPSDO’s, a powered splitter is a really good idea. Each time you split another 2 ways, you loose 3 db. Get at least a 4 way splitter ….
