Please note: In an effort to keep the price on Maco Antennas down, we have decided not to clean up all the
burrs and rough edges on the parts. We recommend that you deburr and clean up each part with files,
sandpaper, etc. so that they go together easily. We are aware this needs to be done but have elected not to
do it to save you the money we would have to add to the price of the kit for this service.

FIGURE 1 GENERAL INSTRUCTIONS
This drawing shows a view of the antenna assembled. The M106C may be used vertically or
horizontally. These instructions and FIGURES 2 through 4 show the correct assembly instructions. It is
highly recommended that rope be put in the elements to prolong their life. All hardware should be tightened
securely, and then coated with silicon rubber sealant or similar compound to prevent loosening from wind
vibration.
Take care to locate all parts accurately per dimensions given. Complete each step as instructed
before going on to following steps.
Upon completion of assembly, install the red plastic cap (PLSR) on the director end of the antenna,
and the black plastic cap (PL5) on the reflector end. This will allow you to determine at a glance the direction
of transmit and receive.

First mark the center of the boom coupler (T53), then slide the unslotted ends of the center boom
sections (T52P) over each end of the coupler so they butt at the center mark.
Attach the boom-to-mast plate (PO 1 P) and the vertical guy support
(VO3P)
at the boom center using
2” U-bolts, saddles and hardware as shown in Figure 2A. Be sure to slip the 2” U-bolt for attaching the guy
support over the boom before securing the mast plate (POlP).
Slide the swaged ends of the intermediate boom sections (T3
1P)
6” into the slotted ends of the center
boom sections. Secure with 2” U-bolts, saddles and hardware as shown in Figure 2B.
Slide the
swaged
ends of the end booms sections
(T32P)
5” into the slotted ends of the intermediate
boom section and secure in the same manner as above. The overall length of the boom should be
approximately 370”. If not, adjust the end sections equally until the overall length is at least 370”.

FIGURE 3 ELEMENT ASSEMBLY AND MOUNTING
Select a frequency in the center of where you work from the chart on page 6 and follow across for
element dimensions “A”
&
“B”.
To assemble the elements, slide a piece of l/2” O.D. tubing (TOl) into each
slotted end of the
5/8”
O.D. center section
(Tl
1P).
Allow equal lengths on each end to arrive at the specified
overall length (Dimension “A”) as shown in Figure 3B. Be Accurate! Verify the overall length.
Slide a boom-to-mast mount (BE2P) to the center of each element before securing the joints with
clamps and hardware as shown in Figure 3A.
Install elements on boom per dimensions in Figure
1,
with U-bolts, saddles, and hardware as shown
in Figure 3B. Be accurate as possible, and be sure the elements are exactly centered on boom before tightening
clamps.

ofthe
eyebolts (N18). Turn

only. These will be used to secure the eyebolts after guy tensioning.
Install
eyebolts
into the top holes of the vertical guy support
(VO3P)
-
one eye each direction. Thread
a hex nut about six turns onto each eyebolt.
Install a egg insulator (EG 1) on one end of each
.762M
(30”) guy cable and wrap it five or more times.
Take two of these cables and install one on each eyebolt leaving
.304M
(12”) between the egg insulator and
the eyebolt, wrap it five or more times and cut off the excess. Take the other two cables with insulators and
wrap each around the boom just in front of the clamp as shown in Figure 4A. Wrap and cut off excess.
Using the remaining two pieces of cable, take one end and thread it through the top egg insulator.
Wrap and cut off excess. Thread the other end through the lower insulator and pull tight enough to remove
slack only. Wrap and cut off excess.
Tension guys by tightening the nuts on the ends of the eyebolts. Secure with the nuts on the opposite
end near the eye.
Line the elements up with the use of a level or any other workable method. Double check the spacing
dimensions and make sure the elements are centered in the boom-to-element clamps. Tighten all hardware
taking care to line the elements up with the use of a level. Check your measurements and make sure the
elements are centered on the boom.

GAMMA MATCH
FIGURE 4 GAMMA MATCH MOUNTING
Mount the gamma match
(GOlP)
to the driven element, using the gamma straps
(ZO2P,
ZO8P)
and attaching
hardware as shown. Attach your 52 ohm coaxial cable to the connector (S42) and dress along boom and down the
mast. The gamma is shown pointing down - this is to let water out.
ADJUSTING THE STANDING WAVE RATIO (SWR)
Refer to Figure 4. The dimensions given are approximate and should be used as a starting point.* The gamma
match has 2 adjustments. First is the capacitor adjust and second is the slider adjust. Connect a SWR bridge
coax
between your transmitter and the antenna and check the SWR.
If adjustment is required, loosen the clamp on the
gamma match and the screws holding the slider (gamma straps
(ZO2P).
Next move the capacitor adjustment first one
direction, then the other until a minimum SWR reading is obtained. If SWR is not yet satisfactory, move the slider
out 2” away from the boom.
Ifthe reading has gone up move the slider
backto
the original position and
then2”
towards
the boom. Now readjust the capacitor for minimum SWR. You should now be able to determine which direction to
move the slider. Repeat the above procedure moving the slider in smaller increments until a satisfactory SWR is
obtained. Tighten all hardware. Disconnect the SWR bridge and reconnect your coaxial cable.
When assembling for vertical use, set antenna on a pole about 8 to 9 feet above the ground horizontally and
adjust SWR to 1.7. When you turn the antenna vertical and mount it on the tower, etc., the SWR will drop to 1.4 to
1.5. This is good; QUIT! Antenna results best if vertical antenna clears the top of the tower.

Installing and rigging towers, masts and antennas require specialized skills and experience. Information
supplied by MACO assumes that all products will be installed by personnel having these skills and have installed
similar products before. No one should attempt to install towers or masts without these knowledgeable skills.
MACO assumes no liability if faulty or dangerous installation practices are used. There are available, trained
and experienced personnel to assist in installation, maintenance, or dissassembly. Contact your local installer if
consultation or assistance is required.
All tower and antenna installations should be throughly inspected at least twice a year by qualified,
experienced, and trained personnel to insure proper performance and safety standards.
An additional warning precaution is given to be careful of surrounding high voltage power wires and other
electrical hazards duing installtion of your tower, rotor, or antenna.
