Subj : Options for HT radio antenna?

I used Plastic twinlead instead of open wire ladderline 
It was made 30 years ago.
I think the tubing (plastic pipe) is 1/2" plastic waterline.
The inside of the pipe is big enough to hold the twinlead.

To get the twinlead into the pipe I put a length of string through the pipe
(think I had a small weight on the end to help drop it through to the bottom),
took the weight off andtied the string to the plastic twinlead so I could pull
it through the pipe.
I don't recall if the coax was attached directly to the twinlead or if there
was some kind of Balun made to match the coax to the 300 Ohm twinlead.

I remember long ago folding up some twinlead to make a balun for another
antenna, I just can't recall if there is a balun inside the J-Pole tubing 
Hmm, after looking in my ARRL Antenna manual a out baluns insted of the
twinlead being folded it probably was a piece of coax I coiled up to match 
a folded dipple yearsago.
Old age is rough, but once a LID always a LID.
