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.

Bob,
can you explain more about the effect of antenna performance on a GPSDO
system?

Now you have told me it is important,  I would like to know more! My lab
has an East facing window.

The only way I would use an external antenna is if I had optical isolation.

I live in an area where the lightening risk is considered low,  but having
lost equipment twice, I am probably more concerned than others might be.

Dave.
