We simply used the commercially available B&W broadband loaded dipole.
Our customer typically ran 1KW into the antenna, and was very happy with
the price/performance. In spite of the negatives often cited about the
antenna, it is a very effective compromise for some situations.

The other reason I don't necessarily want to use the B&W is that with a
little freedom of design parameters and my limited frequency range of
interest (don't need 1.8 to 30 or even 4 to 30, just need 4 to 9), I was
hoping I could adjust the design characteristics to minimize the
inefficiency and mitigate the negatives.
