      While I haven't used one directly myself, I am familiar with the ZR-3.
 The reason that it is rated at 93% efficiency is that it is basically
full-sized vertical dipoles.  They are bent in the flat-top configuration
illustrated in the catalog, thus reducing the overall height of the antenna.

     The advantages include:

     *  Increased efficiency over a conventional trapped vertical (NO traps!)
     *  Increased bandwidth over a trapped vertical
     *  True "NO radials required" (it's a dipole, remember?)
     *  Full legal limit (and more) power handling capability
     *  Can be mounted at any height (2 feet off the ground minimum)

      If I was in the market for a vertical, I'd get one of these in a New
York second.  TOWER TECH is a Force 12 dealer.
