This is undubtedly true- also for type UHF or type F. But why is a contant
impedance connector important for an antenna input at HF? Or anywhere in
an HF receiver? Even in a critical mixer application optimized for 50
Ohms, the small discontinuity at HF from an RCA plug is of no real world
concern.

.... go up in frequency to land-mobile VHF and UHF and look at what GE and
Motorola used for the optional pre-amps -- RCA (phono) jacks and plugs.
This gets covered about every 18 months or so on the Collins list as
newcomers -- make these pronouncements.

I like the audio hobby with $ 40 Cardias caps for RCA jacks.
