Witryna25 wrz 2014 · The refection coefficient due an impedance mismatch is: - R − Z o R + Z o Where Zo is the impedance of the cable and R is the source or load resistance. And, for your 50/75 ohm setup will be -0.2. So the signal you put down the cable of (say) 3Vp-p will produce a reflection of 0.6Vp-p. Is this too much? WitrynaThere's nothing wrong with using 75 ohm coax in particular. It's just that it is conventional for amateur radio equipment to be designed with 50 ohms characteristic impedance, so if you substitute 75 ohm coax without doing anything else you will have mismatches.
