What shape is the melted dielectric in after you get finished with the heat
to solder the copper jacket of the hardline to the adapter?
When the center conductor moved when the dielectric melted, the cable
impedance also changed. When you melted the foam dielectric, you also
changed the velocity factor of the cable.
If the adapter bottoms out against the connector, you can pass the hardline
through the adapter and flare the corrugated shield so that it is
compressed by screwing the adapter in. This would preserve the impedance
and velocity factor of the cable.
