Distance from antenna to front end

Hello,

I'm using the PN512 front end in one of my designs. Our system design would be a lot simpler if I can design an antenna at the end of a 10 inch long cable, instead of trying to cram my front end solution to where the antenna needs to be. Is there a rule of thumb for how long this distance can be? Can I design the antenna following the design videos taking this into account (1-3uH inductance, etc.)? What are the design reasons for not being able to do this (inductance increases too much, series resistance, etc.)?

Thanks

Rob
