Antenna
Decide the frequency at which you need the antenna to resonate and then refer to the appropriate graph for your
model on pages 4, 5, & 6 and Figure 1 on page 3 to determine the dimensions for the next steps:
1. The top section is measured from the top of the section to the top part of the phasing loop. Slide the section
in or out until the correct length is obtained, lightly tighten the hose clamp, twist each of the sections together to
ensure good electrical contact and then securely tighten the hose clamp.
2. The bottom section is measured from the bottom part of the phasing loop to the screw located in the base insul-
ator. Slide the bottom section in or out until the correct length is obtained, lightly tighten the hose clamp, twist
each of the sections together to ensure good electrical contact and then securely tighten the hose clamp.
3. The phasing loop is measured from the bend of the loop to the screws located in the middle of the phasing loop
insulator. Loosen the two middle screws and slide the phasing loop until the correct length is obtained as indicated
on the graph for your model. Tighten the associated screws.
Do not trim
the excess phasing loop from the
other side or the antenna will not perform correctly at lower frequencies.
4. Temporarily set up the antenna in a clear area at least 6 feet above the ground. Apply RF power to the antenna
and check for low VSWR at the chosen frequency. You may then fine tune the antenna by adjusting the sections.

4. For the VG4066 model, Dimension “A” and “B” are fixed at 14.5” for all frequencies, and Dimension “D” (the
hairpin) at 5”. Dimension "C" (radial yoke) should be adjusted per the graph. No other adjustment is necessary.
5. For the VG4506 model, Dimension "A" is fixed at 14.5" for all frequencies, Dimension "B" is fixed at 12.75" for
all frequencies and Dimension "D" (the hairpin) is fixed at 3.75" for all frequencies. Dimension "C" (radial yoke)
should be adjusted per the graph. No other adjustment is necessary.
6. Temporarily set up the antenna in a clear area at least 6 feet above the ground. Apply RF power to the antenna
and check for low VSWR at the chosen frequency. You may then fine tune the antenna by adjusting the sections.
Longer sections lower resonate frequency, shorter sections raise resonant frequency.
