[TenTec] re: Resonant antennas

[Rob Atkinson, K5UJ]

The situation in which open wire feed is especially vital to use is when the 
antenna is used on a frequency below its resonant frequency.  It is in these 
cases that low Z unbalanced line becomes extremely lossy.  Open wire feed 
shows a relatively high loss also, but it is much much less.  It makes the 
difference between a situation where almost no power is getting to the 
antenna v. one in which a high percentage is getting there and radiating.  
For more on this take a look at:

"The Lure of the Ladder Line”, by Steve Ford, QST, December 1993.
