Oh yes, for many years I am also involved with all kind of electronics. So you know there is a huge scam market with HiFi and video cables like the very expensive gold cables for a better sound and picture quality? Even for a simple SPDIF (digital signal) there are special expensive cables with which people do believe it will give a better sound quality as we also see gold plugs for a lower connection resistance of the already high impedance audio line signal.
Yes, with COAX there is indeed an impedance factor although I doubt it is noticeable on the few centimeters of the receiver antenna as I never had noticed with short length 50 ohm cable using for antenna's and 75 ohm cable for network and video. The older receivers with a single wire I have replaced a lot, no issues there, even if the length was not excactly the same. But for an antenna the right length is the most important factor.
