The KL7JR HUSTLER 4BTV It is easy to convert some commercially made verticals to work on the WARC bands. (Also see the K7TUC Mod)
For my mod, I used scrap 1/2 inch plastic electrical conduit to support the vertical wires (the white PVC pipe or other non-conductive material also works), 2 lengths at 2 foot long each, some #14 wire, (see lengths below), a handful of cable tie-raps, something non-conductive for insulators, (I used scrap plastic tubing), and a 1-1/2 inch hose clamp and some string to tie the insulators to the plastic supports. See additional pictures below:
Connect both vertical wires and the center conductor of your coax feed line with a hose clamp (for my portable use I used battery clamps to attach the coax) at the base of the commercially made vertical antenna. Even though some commercially made verticals can be used "stake mounted" without ground radials, I put down ground radials and tie to coax shield whenever I can. For a more permanent mounting, I'd use bolt on connectors over the battery clamps. Don't forget to refer to the original articles in the links above.

"Top Hat" assembly with cross arm showing support attachments for verticals. My Z-100 tuner and TS-50 transceiver easily tuned both wires! In a few hours of operating on my first test outing (fair band conditions) I worked Canada and Mexico plus about a dozen states on each band.
