1. Attach The Base Plates To Tripod
Retrieve 3 base plates and attach them to
the bottom of the nested legs using the
hitch pin attached to the base plate. Retrieve the last base plate and attach it
to the base pole using the hitch pin
attached to the base plate.
Depending on the system, base plates
will be either steel or UHMW
Hitch pin
A. Attach to tripod
B. Attach to base pole
2. Setting The Tripod
A. Open tripod
Open the tripod making sure that the base
plates are flat on the ground and that the lower
collar is fully depressed in a downward
position. The rotational axis of the base plate
should be toward the center.
B. Insert 1 Mast Section
Insert one mast section from the top and secure
in place using the turn handle on the lower
collar.

D. Extend tripod
Extend the tripod by releasing the turn
knobs on the nested legs. Lift until the
tripod lower collar is approximately
chest level.
The pre-drilled holes in the nested leg are for
visual reference only and are used in leveling
the tripod. Do not extend the nested legs
beyond this point or attempt to set the turn
knob screw into the hole.

C. Attach Guy Collar
and guy ropes
Attach guy collar to mast section near the top and
attach the guy ropes as depicted. At this time you
may mount your device either just above or below
the guy ropes.

Important! Use ground stakes to secure any mast system
deployed above 12 feet
3. Level The Tripod
A. Level the tripod B. Use bubble level
The pre-drilled holes on each nested leg can be
used as guides for leveling the tripod. Once the
tripod is generally level minor adjustments can
be made on each leg to achieve more accuracy.
Prior to staking the tripod it is important to make sure that the tripod is as level as possible. If the tripod is not level, as
mast height increases the leaning of the mast will become increasingly obvious. The tripod needs to be raised high
enough to permit the insertion of center mast poles through the lower collar. The nested legs are slightly longer to
permit leveling of the tripod on uneven terrain.
4. Staking The Tripod
Pre-drilled holes Bubble level
Once the tripod is level use the 18”ground
stakes to secure each leg of the tripod. Ground
stakes should be driven in at an angle toward
the center of the mast.
Warning! Be mindful of buried cables when staking the mast.
Staking the tripod increases the overall stability of the mast
and is mandatory when deploying a mast above 12 feet or
when guying is required.

5. Inserting Center Mast Poles
A. Insert center mast poles B. Lift center mast pole
C.
Insert each center mast section through the bottom of the
lower collar. It may be necessary to loosen the turn handle
of the lower collar. Insert additional mast sections as depicted
Lift each mast section high
enough as to permit room for
insertion of subsequent mast
sections.
D.
As each mast section is
inserted to height, the turn
handle may be used to secure
the mast in place.

6. Adjusting The Center Mast Poles
A. Adjusting the ball plunger insert.
Each mast section has an adjustable ball plunger on the
tip. The ball plunger may be adjusted using a flat head
screwdriver. This will reduce rotation of the mast
sections. If the ball plunger is over tightened the mast
section will not nest.

7. Staking The Guy Ropes
A. Position the ground stakes
Retrieve the hammer and ground stakes
And align the stakes out away from the
mast in such a manner as the stake
coincides with the pattern on the top
of the pulley. Each guy stake should
align 90 degrees away from the stakes
on the left and right.
Drive each ground stake into the
ground at a 45 degree angle away
from the tripod. Make sure that
the ring on the ground stake is
facing the tripod.
B. Clip guy ropes to the ground stakes
For optimal stability, you should always guy out at
least 2/3 of the height of the mast away from the base
of the tripod.
28 foot mast - guy out 18 feet from tripod base
32 foot mast - guy out 21 feet from tripod base
36 foot mast - guy out 24 feet from tripod base
40 foot mast - guy out 27 feet from tripod base

DANGER! Contact with overhead wires or power lines can result in serious bodily injury or death
8. Inserting The Base Pole
A. Insert the Base Pole with base plate attached under the last mast section.
Insert the base pole into the
bottom of the last center mast
section and loosen the turn
knob letting the full weight of
the mast rest on the base pole.
9. Complete Guying The Mast
DANGER! Do not over tighten the guy ropes
When guying the AntennaMast be sure not to over tighten the guy ropes. The objective of guying is to
stabilize the center mast section, reduce masthead sway, and provide stability during wind loading. If the guy
ropes are over tightened the downward load on the mast is increased and the overall load capacity of the mast
is reduced and the AntennaMast can become unstable.
A. Adjust the guy rope
Adjust the guy rope by sliding it towards the mast
to tighten and away from the mast to loosen. To
lock the guy rope, place loop the guy rope over
the two hooks on the inside of the rope stay.
Apply tension on the guy rope by sliding rope
stay. Guy rope should be tangle free and snug.
Be sure that the center mast sections remain
straight and perpendicular.

1. Slightly loosen the guy ropes and then loosen the turn knob and remove the base
pole. Lifting slightly on the base pole allow enough space below to remove it
from the mast. Tighten the turn knob so that the next pole remains in place.
2. Remove the next mast section using the same process.
3. Repeat the process for the remaining mast sections using the same procedure as
above until all of the mast sections have been removed. Store the mast sections in
the carry bag.
4. Unclip the guy ropes from the ground stakes and wind them on to the rope stay
until ready to unclip from the guy collar. Remove the ground stakes and store
them along with the guy ropes in the carry bag.
5. Remove the guy collar.
6. Remove the ground stakes from the tripod and store them in the carry bag.
7. Collapse the tripod and allow the nested legs to recess into the tripod legs. Fold
the tripod and tighten the turn handle on the tripod legs. You may find it easier
and quicker to store the tripod with the base plates attached. Store the tripod in
the carry bag.
It may be necessary to remove the slack
from the guy ropes in order to adjust the
tension correctly. Simply pull the knotted
end of the guy rope through the rope stay
until you have removed the slack from the
guy rope.
B. Take up the slack
