Topband: 40/80/160 Meter Antenna

[Jim]

Back in the July 92 issue of QST there was an article by Al Buxton, W8NX,
the described a space efficient 40/80/160 meter antenna.  This antenna was a
trap design that used inner core of RG-58 coax wound on PVC pipe forms.

I want to build one of these antennas but the article was not clear in
exactly how to build the coils.  If somebody has built one of these antennas
and would be willing to entertain some questions, I would appreciate it.

Thanks,
