Hi You need a good antenna setup to get a good disciplined oscillator. The bigger question is if you *need* the sort of “better” it gives you. If you are running a simple TCXO based GPSDO, you will have a number of issues to deal with compared to an OCXO or Rb based system. If “better” is an objective, consider the entire system.
