Voyager® & Voyager® Plus Assembly & Tuning Information
U.S. Patent Number 5,612,705
Introduction
Thank you for choosing the Laird Voyager® Antenna. The Voyager® is a vertically polarized gold anodized base antenna.
This antenna has been designed for accuracy, durability and value. Electrical designs are optimized with the latest in
computer aided technology. All aluminum is gold anodized for extremely high durability, resistance to corrosion and an accurate
radiation pattern. Warning! Use extreme caution when installing this antenna. Electrocution and/or death can occur if this an-
tenna comes in contact with or comes near electric power lines.
Assembly Instructions
Please note we have provided Red Ink Marks as a guide to tuning your antenna to the lowest frequency in its specied band.
2dBi Gain Voyager® Antenna
1. No assembly is required.
2. For quick tuning to the lowest frequency in the band, extend antenna until the red line appears, align the red line with the
top of the next section and tighten the hose clamp.
3. In order to tune to a specic frequency, proceed to the Tuning Procedure section below.
5dBi Gain Voyager® Antenna
1. Locate the phasing loop in the supplied parts bag.
2. Loosen the two middle screws located on the phasing loop insulator. Insert the phasing loop into the holes provided
and tighten the two screws until the phasing loop is lightly secured.
3. For quick tuning to the lowest frequency in the band, extend both antenna sections until the red line appears, align the red
line with the top of the section below it and tighten the associated hose clamps. Adjust the phasing loop until both red lines
are aligned next to the phasing loop insulator on the side the loop is inserted and tighten the associated screws.
4. In order to tune to a specic frequency, proceed to the Tuning Procedure section below.
6dBi Gain Voyager® Plus Antenna
1. Locate the phasing loop in the supplied parts bag.
2. Loosen the two middle screws located on the phasing loop insulator. Insert the phasing loop into the holes provided
and tighten the two screws until the phasing loop is lightly secured.
3. Assemble the radial yoke by rst screwing one lock nut into the threaded end of each of the four radials. Screw the radials
into the four symmetrically placed holes in the radial yoke, then rmly seat the radial lock nuts into place. Slip the radial yoke
over the mounting sleeve above the red lines on the sleeve. Tighten the two locking screws to secure the yoke to the sleeve.
4. For quick tuning to the lowest frequency in the band, extend all antenna sections until the red line appears, align the red
line with the top of the section below it and tighten the associated hose clamps. Adjust the phasing loop until both red lines
are aligned next to the phasing loop insulator on the side the loop is inserted and tighten the associated screws.
5. In order to tune to a specic frequency, proceed to the Tuning Procedure section below.
Tuning Procedure:
Important Note: When attaching the transmission line take care not to block the three drain holes located around the connector
at the base of the antenna. These holes allow condensation that develops inside the antenna to drain, enabling proper operation.
2dBi Gain Voyager® 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. Using a tape measure, measure from the top of the top section to the screw located in the base insulator.
2. Loosen the hose clamp and slide the section in or out until the proper 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. 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.
4. To increase the frequency, reduce the overall dimension of the antenna by sliding the section down.
To lower the frequency, increase the overall dimension of the antenna by sliding the section up.
5dBi Gain Voyager® 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 ne tune the antenna by adjusting the sections.

4. For the VG4066 model, Dimension “A” and “B” are xed 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 xed at 14.5" for all frequencies, Dimension "B" is xed at 12.75" for
all frequencies and Dimension "D" (the hairpin) is xed 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 ne tune the antenna by adjusting the sections.
Longer sections lower resonate frequency, shorter sections raise resonant frequency.
