Bob, I think a more accurate description of several coiled turns of coaxial cable would be a RF Choke, serving to limit common mode currents on the outside of the coax cable. Norm W4QN == In a messag
That's an Alice In Wonderland view of things. Yes, the coil of coax is an inductance in the common mode circuit, but the common mode circuit also includes the series impedance of the transmission lin
Norm, Correct, it is an RF choke. A BALUN works as an RF choke in series with the outside of the coax shield Bob _______________________________________________ ______________________________________

I have some modelled examples on my web site which illustrate the effect Jim is talking about. Take a look at the section "Why reactive chokes are undesirable" on this page: http://www.karinya.net/g3
