I'm just saying that there is no fundamental reason (engineering/physical chemistry/ E&M etc etc) that I can think of on why copper is bad and aluminum or tin or steel etc is better. I'd be really interested to know why if there is indeed a why (if someone knows, please post). I fully get that a poor braid can be problematic, but I am perplexed as to while copper would be problematic as a metal.
My guess is that your experience with copper braided cable had bad braiding and the other cables which had X other metal had better braiding or multiple levels of shielding. I've seen braiding have 55% up to 98%(?) shielding. For example, Belden 89259 has 95% www.bluejeanscable.com/pages/technicaldocs/89259tech.htm
This cable is pure copper and has been used by tons of DIY "audiophiles". You'd think that if it was the copper, that these "golden ear" types would have heard the radio problems and have trashed it the moment they could.
Beldon 9201 (all copper) is an RG58 with only 78% shielding and was pretty common before in data transmission.
I wish I could find or could explain in more detail as to why. All I know is dish network I worked and coper was a bad thing......Also I worked for 2 cable companies and still work for Comcast. And at every place I have worked. Copper is a big NO. It has to almost always be removed for the cable or satellite to work properly. I have seen million dollar houses wired with copper braid cable tan we then have to tell the owner sorry but your cable sucks and needs replaced. Thats is. In theory it may sound good and read good to you guys. But in Practice for someone that uses it every day. I know better than to use it. Atleast for cable and satellite use. Because it does not block out ingress/egress as well as aluminum braid and sheild. Im no scientist so I cant explain why. But I will ask any of you that think im wrong. Please call your cable or satellite provider and ask them to come install copper braided coax in your house and see what response you get. And dont get mad when they either laugh at you or tell you that your crazy and it wont work. SOmeone please do this. I want to hear how it goes. lol
