Congratulations!
You have just become the owner of one of the finest antennas available. Before beginning assembly,
please
check all parts against the Parts list (Page 2).
Before
any antenna is put into stock at Wilson Systems, Inc., it goes through a complete quality
control check. The final step in this process is aweight check to assure that all parts are present.
In each Hardware Bag, you will find asmall tag with an
inspector number. On the top of each an-
tenna canon, you will find a date/weight stamp with date of packaging, weight and the weigher's initials.
In
the unlikely event you receive an antenna with adefective or missing part, please contact our
Customer Service Department. We will need the Quality Control information mentioned above to properly
serve
you and to correct any quality problems we may have.
After all parts are accounted for, you will need the following tools for assembly:
1. Apencil or other marker.
2. A carpenter's level.
3. A standard blade screwdriver.
4. A3/8" wrench or rachet with 3/8" socket.
5. (2)7/16
II wrenches or one 7/16 II wrench and one rachet with 7/16 II socket.
6. A1/2 II wrench or rachet with 1/2" deep socket.
7. Agood metal tape measure at least 50 f1. long.
In this
antenna kit, you will find abag of Penetrox. This substance should be applied to all tubing
which is telescoped into another section of tubing at points of contact. Before applying the Penetrox,
roughen
the surface to which the compound is to be applied with afine grade of sandpaper or steel wool.
.
Cut one corner off the bag and work the Penetrox into and out of this corner. Apply athin film to the
prepared tubing, then assemble clS per the instructions. The Penetrox will prevent corrosion build-up be-
tween telescoped
aluminum tubing.
All Wilson amateur antennas are supplied with Poly Rope to be installed inside the elements. When
installed inside an
element, the rope absorbs vibrations caused by continuous ground vibrations and winds.
(Trapped elements do
not require the rope since these vibrations are absorbed by the traps.)
We would like to know what you think of our antennas! Of prime importance to us is your valued
opinion as
to quality of materials used and workmanship. We would also appreciate your comments on
performance. Towards the end of this manual you will find agraph for plotting SWR curves with room for
any additional notes you may wish to make. You will also find a questionnaire. We would appreciate it if
you would fill it
out and return it to us. Remember! ... We want to give you a top quality product at a
good price
and comments to'wards that end are always welcomed here at Wilson Systems, Inc.

PRELIMINARY INSTRUCTIONS
For the best results and the best use of your time, familiarize yourself with all parts and instruc-
tions before beginning assembly.
Begin assembly
by unpacking everything and checking all your parts against the parts list. Do not
proceed untH you have determined that you have everything on the list, and each item in the
quantity specified. If anything is missing, contact the Customer Service Dept. at Wilson Systems
immediately, and tell us exactly what is missing. Do not begin assembling your antenna until you
have all parts in hand.
Read
your instructions completely, and be sure you understand them, before you start. Do not
begin assembly until you are sure you have ample time to finish - a partially completed antenna is
especially prone to damage, and parts scattered around are easily lost.

1. Put the boom together as shown In Figure 2.;..,~"'-_r"z:-
2. Then assemble each element as shown in Figures 3, 4, and 5. Mount each element loosely on thE; ~~. c"
boom as soon as it is assembled. locate them only approximately, and do not put the plastic caps
on the ends at this time.
3. After
the elements are all in place, move them to their exact positions, set them square to the boom
and parallel
to each other, and tighten aU bolts and clamps. Recheck all dimensions, and correct any
errors. Be sure the W-clamps for attaching the shorting straps are installed as shown in Figure 6.
Assemble
the beta match per Figur;e 7.
Install
the guy cables per Figure 9.
Recheck all dimensions again, and check the tightness of all bolts and clamps. Coat aU bolts, screws,
and nuts with silicon sealant.
Put plastic caps on the ends of boom and elements.
7. Attach
your coaxial cable to the RF Choke as illustrated, and secure to the boom with tape.
8. Install the antenna on the mast per Figure 9. Dress your coaxial cable down the mast and secure in
several places with tape.

After total assembly it
is extremely important to measure the overall lengths of aU elements. Adjust the
tips of aU full size elements equally on both ~ides to.obtain the correct dimension and inside the traps on the
trapped elements. . _
Vibrations
in your antenna due to light winds will cause the elements to sing and herden. If the ele-
ments over-harden they will become brittle and crack.
In order to increase the life of your antenna, we
recommend
the use of 5/16" polypropylene rope threaded through the elements as described belqw.
Thread
the rope through the 7/S" 0.0. tubing. Epoxy giue the rope to the inside of the tubing which
will have
the mounting plates attached. After the glue has set, thread each piece of the assembly onto the
rope (clamp. tubing. clamp, tubing, etc.). When the entire element is assembled, dimensioned, and all hard-
ware tightened.
epoxy the other end of the rope to the end tube._Cut the end of the rope flush with the
tube and place the plastic cap on the end.

Assemble
one 5/16" hex nut (N01) to each of the four eyebol~~ (N l8P). Turn the nut all the way up
to the eye -as far as it will go with light pressure only. These will be used to secure the eyebolts after guy
tensioning.
Install
two eye bolts in the top holes of the vertical guy support (V03P) - one eye in each direction.
Install one eyebolt in the top hole of each of the two guy mounts (BG2P) - with the eyes towards the cen-
ter of the boom. Install each bolt by inserting the end about ~" (12mm) through the hole, and threading a
hex
nut about six turns onto the end.
Install the guy cables between the eyes, as shown in this figure and in Figure 1. Allow approximately
equal lengths of cable to extend through the eyes on each end, pull tight enough to remove the slack only,
wrap six or more times, and cut off excess.
Tension
the guys by tightening the nuts on the ends of the eyebolts. Tighten equally on both ends of·
each guy,
and secure with the nuts on the opposite sides.

Place the center
of the director element 3" (O.016m)
from the end of the boom.
~.
For exact element di mensions
see Figure 4
-----------
Put the boom together as shown in Figure 2.
Then assemble each element as shown in Figures 3, 4, and 5. Mount each element loosely on the
boom as soon as it is assembled. locate them only approximately, and do not put the plastic caps
on
the ends at this time.
After
the elements are all in place, move them to their exact positions, set them square to the boom
and parallel
to each other, and tighten all bolts and clamps. Recheck all dimensions, and correct any
errors. Be sure the W-clamps for attaching the shorting straps are installed as shown in Figure 6.
Assemble
the beta match per Figure 1.
Install
the guy cables per Figure 9.
Recheck all dimensions again, and check the tightness of all bolts and clamps. Coat all bolts, screws,
and nuts with silicon sealant.
Put plastic caps on the ends of boom and elements.
Attach
your coaxial cable to the RF Choke as illustrated, and secure to the boom with tape.
Install
the antenna on the mast per Figure 9. Dress your coaxial cable down the mast and secure in
several places with tape. ~

NOTE: These dimensions are progressive dJ
starting from the 20m 2nd Director Element.
After
total assembly it is extremely important to measure the overall lengths of all elements. Adjust the
tips of all full size elements equally on both sides to obtain the correct dimension and inside the traps on the
trapped elements.
Vibrations in
your antenna due to light winds will cause the elements to sing and harden. If the ele-
ments over-harden
they will become brittle and crack. In order to increase the life of your antenna, we
recommend
the use of 5/16" polypropylene rope threaded through the elements as shown below.
