J pole question
Harbin, You seem to understand the "J-Antenna". What you really seem to be asking is how far apart is "too far" for a balanced transmission line. That's a question I can't answer and I'm sure others can, but , in the common custom of adding obtuse references which sort of seem to be relevant... what about that old one wire transmission like the "G-Line"? [no joke] 73, Steve, K9DCI "Harbin" wrote in message ... Howdy: In a j-pole the 1/4 wave element, and the bottom 1/4 of the 3/4 element should act as a transmission line, right? So... shouldn't these elements be as very close to each other to cancel one another out, closer than what I see on most j-poles? Or is this space have something to do with the impedance of the antenna? -- SeeYaa  Harbin Osteen KG6UROThis is YOUR futu http://halturnershow.com/aztlan_caps.wmv http://media.putfile.com/La-Gran-Marcha The Mexican Solution: http://www.centerforsecuritypolicy.o...s&code=06-D_18 - |

J pole question
Nope. Only read about it and, perhaps, understand the theory.
