[Wswss] j-pole antennas---feed point question

[Len Gwinn]

QUESTION  from  WA6KLK

In building a few copper j-poles for a few friends for the fm bands,  I have a VERY confusing point.

Some of the schematics show the center conductor of the coax to the short leg of the j,  others show it to the long leg of the j.

Why the difference ??    Does it make any difference  ??

I can build them but now am  a bit confused for the feed due to the many many  designs of feed, ie, which conductor to which leg of the j.  I have done both and not really noted a difference but why ???  

Common thinking by a couple of folks here is that the center connector should be to the short leg, ie, like the feed of a gamma match or shuch on a beam.    ----    Then again, a couple say feed the center conductor to the long leg as that is the "hot" leg and "more" metal in the air.

Thanks and any other information as to why would be appreciated  !!

Thanks !!!
