Introduction

Thank you for choosing the Antenex
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.

Assembly Instructions

Please note we have provided
2dBi Gain Antenna
VOYAGER™
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 specifi c 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 specifi c frequency, proceed to the Tuning Procedure section below.
6dBi Gain
VOYAGER™ PLUS
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 fi 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 fi 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 specifi c 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.
