[TowerTalk] X9 / Skywalker
Sat, 29 Jan 2000 19:48:49 -0600
Cushcraft used the name "Skywalker" to refer to
their HF previous line of mono-banders. I'm not
sure if this refered to both the 4L and 3L versions
or only the 4L monobanders.
Incidently, their advertising claimed a 2 dB difference
between the 3L and 4L Yagi's. My antenna program
showed a difference around 0.5 dB.
The second director was noticably shorter than the
first in the 4L design. This resulted in improved F/B
but less than optimum gain. Lengthening the second
director to be equal in length to the first director would
increase gain approximately 1 dB but reduce F/B and
necessitate readjustment of the gamma match.
