I personally am reluctant to use the solderless crimp-on type of connectors. I have seen too many contribute to radio failure. Soldering a PL-259 radio antenna connector on an antenna cable may be a ...

RG58 is worse than the PL connector, I think. Better use RG213UBX, RG214, H155 etc. RG-58, for what I know, has not only loss but also poor shielding by todays standards.

An SMA edge connector may be designed to present a characteristic impedance of 50Ω typically, but that is to the end of the connection pins. Once it’s soldered down, there is a discontinuity ...
