Robert, I bought my heavy-duty broadcast version of the 5/8 wave j-pole years ago from the guy that still sells the 2M version on eBay, KB9VBR. To this day, he still shows the picture with the feed line going the wrong way, and for anyone that asks, the center conductor goes to the longer element, it is the radiator. That being said, there are others on eBay selling broadcast-band ready j-poles, or build your own from http://www.aralb.org/Commitees/Technical/J-POLE/design_a_jpole_antenna.htm
I have never tried ladder line, don’t see why it wouldn’t work with stiff copper wire, EMT, or even speaker wire stapled to the wall. All I can say is the darn thing works great with the little EDM transmitter, and from inside my garage with the door closed, is getting out between 3/4 and 1 mile in every direction.
