[TowerTalk] Transmission Line Theory and Practice

[N4CW at aol.com]

Given: (1) a length of hardling (1/4 wave, 1/2 wave, odd length, open-ended
(2) from a 50-Ohm source, feed just the center conductor of the hardline, 
leaving the outer jacket unconnected to the source ground     

Questions: (1) What's expected to happen to the r.f. inside the coaxial 
section --
(a) it's my understanding that the SWR should be infinite -- will the r.f. 
couple to the INSIDE of the jacket, OUTSIDE, or both? Neither?
(b) will this property be exhibited in a resonant 1/4-wave or 1/2-wave 
length? In other words, does it matter how (practially) long the hardline is?

Purpose: to create a radiator from hardline by a means other than attaching 
to the outer (aluminum) jacket.

Thanks,
