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 MlOSC 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 (PL4R) on the director end of the antenna,
and the black plastic cap (PL4) on the reflector end. This will allow you to determine at a glance the direction
of transmit and receive.

FIGURE 2 BOOM ASSEMBLY
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 1P) and the vertical guy support (VO 1P) 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 end booms sections (T32P) 5” into the slotted ends of the center boom
section and secure in the same manner as above. The overall length of the boom should be approximately
309”. If not, adjust the end sections equally until the overall length is at least 309”.

FIGURE 3 ELEMENT ASSEMBLY AND MOUNTING
Select a frequency in the center of where you work from the chart on page 7 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)gg Allow equal lengths (Dimension "B") on each end to arrive
at the specified overall length (Dimension “A”) as shown in Figure 3B. 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. Mount the first reflector with the u-bolt facing the rear, mount its mate with the u-bolt facing the
front of the beam - the horizontal and vertical elements should be close together at 1/4" apart. Do this for all
the elements.

FIGURE 4 GUY ASSEMBLY
Cut four pieces of guy cable .762M (30”) and two pieces 2.082M (82”). Assemble 5/16” hex nut
(NO 1) onto each ofthe eyebolts (N18). Turn thenut all the way to the eye; as far asit will go with light pressure
only. These will be used to secure the eyebolts after guy tensioning.
Install eyebolts into the top holes of the vertical guy support (VOlP) - one eye each direction. Thread
a hex nut about six turns onto each eyebolt.
Install a egg insulator (EGl) 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.

FIGURE 4 GAMMA MATCH MOUNTING
Mount the gamma match (GO 1P) to the driven element, using the gamma straps (ZO2P, ZOSP) 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.
NOTE!
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.
