ANTENNA
®@ Description
Newly developed Linear Phase Shift technology and
Direct Joint structure by three-piece FRP outershell
enable to achieve the following performance.
1)2m 5/8 wave three-element C-Load and 70cm 5/8 wave
eight-element strucutre.
2)High performance and high maximum power
rating at 2m and 70cm bands.
3)Low vswr and broader coverage at 2m and 70cm
bands.
4)Overlapping three-piece FRP outershell structure is
strong enough to compete with one piece structure.
5)Ring gasket provides perfect waterproof.
6)Ideally tapered FRP outershell has enough thickness
to withstand strong wind and avoid unwanted QSB.
7)Joint bracket can be fastened securely by special
wrench attached.
8)DC ground structure of the antenna protects
transceiver from high voltage caused by thunder
lightning.
9)Feedpoint connector is being exposed downward at
the bottom of support pipe to make antenna
installation or detachment easier.
10)With optional 2m/70cm duplexer, two bands can be
transmitted simultaneously, or one band can be
transmitted simultaneously while receiving the other
band.
@ Assembly
Note ; Be sure to assemble from upper element. If the
antenna is being assembled from lower element, element
can not be pulled out from outer shell and fastened
properly.
1)Put special wrenches on upper and center FRP
outershells as shown in the Fig. 1. Use small diameter
section of the wrench.

2)Connect upper element in the upper FRP outershell
and center element in the center FRP outershell with
screwdriver.

3)After connecting these two elements in the outershells,
fasten upper FRP outershell joint bracket with special
wrenches as shown in the Fig. 3.
Fasten the bracket thoroughly until there is no gap
between each part of the bracket.
4) After fastening the bracket, detach the wrenches from
the outershells as shown in the Fig. 4.
5)Connect center element in the center FRP outershell
and lower element in the lower FRP outershell the
same way as section 2,3 but use larger diameter section
of the wrenches at this time as shown in the Fig. 5.

6)Attach three radial elements with the wrench as
shown in the Fig. 6.
7)Attach mast brackets on support pipe and fix them.
8)Attach assembled antenna on mast as shown in the
Fig. 8.
In installing the antenna be sure to take whole balance
into account.

9)Then connect coaxial cable with N connector to
feedpoint section at the bottom of the antenna through
waterproof sleeve as shown in the Fig. 9.
10)After connecting coaxial cable, fix waterproof sleeve
to the bottom of support pipe with a screw.
Turn connected coaxial cable once to make a loop at
right below the antenna as shown in the Fig. 10 to
escape excess load from the cable.

@ Adjustment
The X500HNA antenna is completely adjustment free. If
vswr of the antenna is extraordinary high, most likely,
it is due to coaxial cable and connector contact, or
connector soldering problem. And be sure to use 502
coaxial cable to feed the antenna.
@ Note;
Though the X500HNA is DC ground structure, circuit
across the inner conductor and outer conductor is open-
circuit when measured by a volt-ohm meter. If it is
close-circuit, confirm coaxial cable connections well.
Use the antenna vertically. If the antenna is tilted, it can
not perform perfectly as it is expected.

FOR YOUR SAFETY
Read the following safety precautions before
start assembling the antenna.
eAssemble the antenna on the ground or wide and flat place
such as on balcony before installation.
eDo not assemble or install the antenna on a place where you
can not have enough distance from any electric power lines.
eDo not install the antenna on a rainy or windy day.
eDo not attempt to install the antenna only by yourself.
Installing the antenna alone onthe roof may lead you
dangerous accident. Always ask your friends for help
installing the antenna.
eDo not use iron or aluminum ladder at areachable distance
from any electric power lines.
eDo not install the antenna on a mast which is not grounded .
properly.
eDo not have your family members or friends touch or come
close to the antenna, unless they have realized its potential
danger.
TO AVOID FATAL ACCIDENT
eDo not attempt to sustain the antenna, or any part of support
structure if it begins to fall down. Let it fall by itself.
Do not attempt to remove or restore the antenna or any part
of support structure if it touches a electric power line by
chance. Let it be as it is, do not touch it, and call your local
electric power company immediately.
IN CASE OF AN ACCIDENT
eDo not touch a person or an animal who is or seems to be
in contact with the antenna or any support structure which is
fallen on alive eletric power line. Touching one may lead you
to be electrocuted.
eDo not attempt to separate a person or an animal who is or
seems to be in contact with the antenna or any support
structure which is fallen on a live electric power line by
yourself. Call or have someone call a police officer,
ambulance, doctor immediately.

INSTRUCTIONS
ANTENNA INSTALLATION PRECAUTIONS
To determine antenna installation location, there are several
factors to be taken into account. First thing is antenna
propagation direction to specific target stations. As to whether
there is any obstacles such as tall buildings on the line of sight.
Next is specific installation location. As to whether specific
location is adequate in terms of antenna support and sur-
rounding safety.
Minimum distance to power lines
Twice the length of antenna assembly
eDo not attempt to install the antenna by yourself if you do not
have any experience in installing base station antenna. Ask
your experienced friends or professional for help.
eDo not attemptto install the antenna at alocation where does
not have enough distance from nearby electric power lines.
It is advised to install the antenna at least twice of total
antenna height from nearby electric power lines.
eDo not install the antenna on any type of tower, pole or
telescopic mast which exceeds 30 feet high, if you do not
have enough experience in installing the antenna on that
kind of location. Ask your experienced friends or
professional for help.
eDo not use more than 1/10'sectionif you install the antenna
on iron plumber’s pipe. Attach guy wire if multiple pipes are
used to install the antenna.
