For a broadband dipole, try feeding with 1 wavelength of 50 ohm coax and
1/4 wavelength of 75 ohm coax. Connect 50 ohm coax to dipole, connect
quarter wave section to other end of 50 ohm section, connect any length
of 50 ohm coax to shackward end of quarter wave section. Cut dipole for
midband. You might like this. It only works for heights for which the
dipole impedance is near 70 ohms or more, but I put one up at 50' and it
was very useful for SS.
There have been some postings on Towertalk about this, check archives.
