[R-390] The final word on the R-390A mini-bayonet connector

[Jon Schlegel]

Hi All,

I remember reading someplace that the cable used in at least some of 
the paths in the 390's is higher impedance than 50 ohms or even 75 
ohms.  Unless the path is operating as an actual transmission line 
(termination impedance = cable impedance), a lower impedance cable 
may add extra shunt C to the circuit.
