A materials question for Lex or any of the other clever RF guys here...
I have lots of old coaxial cable I was planning to scrap after I rebuilt my TV antenna. If I take three pieces of the solid copper core, anchor at one end in a vice and twist these tightly from the other end using a drill they form a very stable twisted wire, even more stable if the ends are tinned with solder. OK so it was a quiet night for TV programming yesterday, maybe I need to get out a bit more!
Anyway, in terms of RF and an antenna like this ground plane example, is there a difference in the way this 3 x twisted copper wire will behave compared to solid brazing rod for example?
I have a few N connectors on order so should I try this idea or is it doomed to failure by design?
Thanks in advance
