Tom and All,
I also use phono connectors on some older radios. I'd prefer to substitute BNC
connectors but I don't want to modify the equipment.
What I find helpful is to squeeze the shell of the plug so that it will fit
tightly on the female receptacle and cover the shell with heat shrinkable
tubing so that the pressure is always applied to the connection.

Because I use phono plugs that really have improper shield grounding
integrity, and sometimes the pressure connections add a tiny bit of unwanted
shield impedance to the groundplane of "the box entrance", I use high
impedance beads on these particular cables. I also, as a practice, keep an
eye on those connectors. I use those connectors by necessity, because
several of my radios use phono plugs for external antenna ports, and there
is no easy way to change connectors.
