ADDITIONAL KHF 950 INSTALLATION OPTIONS
While the standard KHF 950 system requires a wire antenna of only
10 feet, shorter wire antennas as well as “shunt” or “notch” antennas
may also be tuned with additional hardware.
Special hardware is also available to allow dual KHF 950 systems
(Figure 2-7) to operate from a single antenna and provide a dual
receive capability.
