And this is a typical reaction as many people on this forum. You think you know it all but actually with this post you show that you have no clue how it really is. You really think the antenna wire is something special made from golden locks weaved by elves at full moon? Wake up and see it is just an every day cheap wire. With older receivers just a simple wire and with later receivers a coax cable.

I have no clue? I have over 35 years experience in the electronic industry repairing video,pinball,home entertainmet,and proaudio. Wire may be simple in your world but there are many factors that go into wire choice including impedance and capacitance but if you want to pass on bad advice be my guest .Kirt out.

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.

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.

I consider myself very humble BUT when someone says I have no clue what I'm talking about when I actually do know.What would you do? Most of the time on R/C forums I ask questions, this time it was in my roundhouse and people say I don't know what I'm talking about.Read the entire thread.
