Which RF Connectors to "Standardize" for Home Lab?

<< < (6/6)

NT0Z:
David and the gang,

The RG-178 comment is unexpected, as I acquired a 500-foot spool of RG-178 about 20 years ago, ostensibly to create interconnects between homebrew PC boards, etc.

I have a metal ratcheting crimper, and I can get the appropriate die if I don't already have it. But I'm wondering about which crimp connectors to get, as RG-174 and RG-178 differ in diameter?

Also, RG-178 has lots of attenuation, even at 50 MHz. Is that a factor when making measurements, connecting instruments, etc?

Thank you,

--Kirk, NT0Z

Obviously the specific connector has to be made for RG-178, but I have not had any trouble finding them.  I have the Paladin Tools CrimpAll and a set of dies for the common coaxial cable crimps down to RG-178.

I have only used it for short lengths and mostly for carrying pulses rather than RF.
