- It still might be a vertical half-wave dipole - remember the "bazooka"
- design, in which the feed is *through* the end, with the feedline going
- through a cylindrical element to the mid-point, and then the outer conductor
- ties to the "pipe" you just passed through, while the inner conductor ties
- to the upper element. In this case, no radials would be required or
- desired. The point is, your blanket statement regarding radials needs
- some disclaimers - there ARE vertical designs which fit the description
- given but which SHOULD NOT be used with radials. The first place to check
- in this case, given that it's a commerical design, would be in the owner's
- manual, or lacking that, a call to Shakespeare.
