The remainder are by broadband antennas (2 - 6, 4 - 12, 10 - 30 MHz)
These broadband antennas are fed through matching networks that had to
bring them within the 3:1 circle on the Smith Chart. During inspections,
we had to sweep them and we reported any that failed. (Some of our tasks
were find-and-fix, most were not.)

Interesting. I wonder if that could be the solution to amateur
installations,
a set of broadband dipoles, but perhaps swept smithchartwise to better
than 2:1?
