What would be a good way of making this connection?


Do you have a scope and a pulse generator? If so, just make a simple
TDR (Time Domain Reflectometry) setup to measure the reflection from a
un-terminated or shorted far end of the cable. You will get much more
accurate results with substantially less effort.

Don't get me wrong, the MFJ-259 is a good instrument. It's just that TDR
is so quick and easy and unambiguous for propogation delay measurements.
