[Elecraft] OT: Balanced Feedlines

[Joe Planisky]

I know it doesn't answer the question you asked, but RG-8/RG-213 has a  
loss of about 0.85 dB/100 ft at 20m. Your 3:1 SWR will add a little  
less than 0.4 dB additional loss for a total loss of 1.25 dB.  Is the  
added hassle of running balanced line worth the extra 1.1 dB?  Are  
there other reasons you want to use balanced line?
