I just made a 2m jpole antenna out of 1/2" copper pipes, like this one:

On this web site the center conductor of the coax is connected to the
longest pipe and the shield to the shortest.

Now looking at other sites I find the center conductor connected the the
shortest pipe.

So what is the correct way to connect the coax?

My year 2000 ARRL handbook has instructions for a copper pipe 2-meter
j-pole, and the author says it doesn't matter which pipe you connect
the center conductor to. (He does mention a coax choke: 3 turns of
coax in an 8-inch coil, held together with tape.)
