HFp Vertical Configuration Table
This is the Configuration Table for the HFp sitting on the ground, out in the open. The same
table appears on the Laminated Card.
Note that the length specifications for the extendable whip are in “Sections”
.
The whip fully
collapsed is one “section” long
.
The whip fully extended is six “sections” long.
Each different configuration calls out specific settings for the Elements, the Radial Wires, and
the Whip. But, it is important to remember that these settings were determined with the HFp set
up in an open area, away from any objects.
The HFp may be affected by nearby objects (within a half-wavelength) in any particular location,
and the specified settings may need to be modified. If this is the case, the settings in the
Configuration Table may be deemed “starting points” for resonating the HFp at your frequency.
I
n some situations, where there are nearby objects strongly affecting the antenna’s resonant
frequency (typically lowering it), shortening the whip all the way may still not bring the SWR to
its lowest level. If this is the case, you may have to re-configure the elements. See the
"Frequency Adjustments" section for information on how to change the antenna configuration to
raise or lower the antenna’s frequency.
Be sure to notice the orientation of the stripes on the two-stripe and three-stripe elements. They
are always specified as “stripes-up” or “stripes-down”. Remember that the one-stripe and zero-
stripe elements may be assembled either “up” or “down”.
In the table, the bottom element is the one screwed onto the base insulator.
