Jim, You say that foam dielectric is more costly and provides no benefit at h-f. If you are only considering dielectric loss this is true, but the lower effective dielectric constant allows (requires) a larger center conductor (for the same overall diameter) which fulfills your "big copper" idea.
On a related note, this increased center conductor diameter also requires special connectors sized for the cable. Wes ps. Your first draft says, "Second draft" If you look at my website, you'll find a first draft of a tutorial on coax and stubs that addresses this issue. Any comments you might have would be appreciated. http://audiosystemsgroup.com/Coax-Stubs.pdf ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
