Thank you for purchasing our products. Be sure to read the manual, it is
important to know the product better to get the most out of it.
THE ANTENNA PARTS
-The boom has 2 parts.
-The larger “u” clamps are the supports for the elements.
-Take a good look at all the components and familiarize yourself with them.
-Aluminum tubes are identified with colors
-GREEN –DIRECTOR (D)
-RED –DRIVE (I)
-BLUE –REFLECTOR (R)
REQUIRED TOOLS
- Assembly
Few tools required for assembly are these:
-Spanners, 10/11 mm and 12/13 mm and set Phillips screwdrivers
-5 m tape measure
- Soldering iron
- Connection
The connection of the coaxial cable is of the “open” type, strip the coaxial
cable approximately 10 cm, separate the mesh from the center of the cable,
and solder the terminals that come with it.
Use self-amalgamating tape to protect the terminals and the cable from
rainwater.

CHOOSING THE BEST LOCATION
- The installation location is very important.
- Make a plan of all the actions you will take to install the antenna, if
necessary, ask for help from professionals.
- Choose the location looking for the greatest distance from trees, metal
structures, power lines, other antennas, distance from people, etc. The
proximity of these elements can reduce efficiency and make installation
difficult.
IMPORTANT
- Don't forget the security procedures.
ASSEMBLY
Assemble the DXW3-30 following the instructions as per the diagrams and
illustrations, assemble the boom first, then the elements, place the elements on
the boom, make the alignment, connect the coaxial, measurements and
adjustments and finally attach to the mast.
The cable connection is open type, see the shock detail in figure 2, it can be
done with the coaxial cable itself, strip 10 cm and separate the wires, solder
the terminals and leave only 20 cm of space until the start of the shock, they
are 12 turns in a diameter of 15cm, use a form for the turns to be well made
and parallel, DO NOT use cell cables as the dielectric is made of foam and can
deform when making the turns, thus altering the impedance, impairing the
functioning.

ADJUSTES
If there is a need for adjustments, make small adjustments to the drive element in 1 band at
a time, increasing if you want to lower the resonance frequency or decreasing if you want
to up the resonance frequency, as the adjustment of one band can interfere with the
adjustment of another band, always mark what you are doing and then put the same
measurement on the other side of the antenna.
Use a good meter that is reliable. Stay away from the antenna during measurements as your
body can cause an erroneous reading. A SWR of 2:1 or less is satisfactory and will not
decrease efficiency, if greater than 2:1, do a general check on measurements, position of
traps and connections.
The SWR check must be done with the antenna pointed upwards and preferably supported
on something insulating 50cm from the floor (it can be a wooden box, a chair, etc.
Measurements with the antenna close to the ground are wrong and will not hold up when
raising the antenna.
The ideal height for installation is ½ wave from the ground or buildings, if you do not have
this possibility, use ¼ wave or at least 1/8 wave, however the efficiency and bandwidth can
be changed.
Remember, biger antenna, lower frequency or smaller antenna, higher frequency.
Find the resonance point on the antenna (smallest SWR) and use this reminder to see if you
need to raise or lower the antenna to get the frequency you want as the center.
Raise the antenna and, if necessary, repeat the operations, the time invested in the
adjustments returns in quality of operation.
