2. Safety Precautions
2.1 General Safety Precautions and Procedures
2.1.1 Never take short cuts
2.1.2 Never install a tower near power lines
2.1.3 Never work alone, always have at least one other person present
2.1.4 Never install a tower on a windy day, during a rain storm, or any time there is a likelihood of
lightening
2.1.5 Never climb the tower
2.1.6 Never raise or lower the tower when surfaces are iced
2.1.7 Never overload the tower by exceeding the antenna sail area or weight limit
2.1.8 Never reach into the center of the tower
2.1.9 Never try to catch the tower should it start to fall
2.1.10 Never use the raising fixture unless the tower is fully retracted
2.1.11 Never modify any parts of the tower or its accessories
2.1.12 Never get oil or grease on the manual winch brake disc fibers
2.1.13 Never rotate the antenna while raising or lowering your tower
2.1.14 Always check for underground gas lines, telephone lines, or other buried utilities
2.1.15 Always lower the tower to the fully retracted position if the wind is expected to exceed 50 MPH
2.1.16 Always use the proper tools and safety equipment
2.1.17 Always contact the power company if the tower, metal ladder, or any other objects come in
contact with power lines. Do not remove them yourself.
2.1.18 Always keep the tower and all components well maintained and inspected for wear or damage
that might lead to equipment failure or injury
2.2 Site Safety
2.2.1 The proximity of electrical lines to the installation site is extremely important. The nearest
electrical line should be at least two times the tower height from the tower center line.
2.2.2 Soil conditions that will allow for a good foundation and access to the tower under all weather
conditions. In many cases the information on soil types or best configuration is available from the
agency that will issue the building permit. Follow all OSHA, Local, and other safety requirements.
2.2.3 The tower should be located as close as is practical and safe to the related equipment.

3.1.7 Pour the concrete into the form (must be a continuous pour).
3.1.8 Assure that the Anchor Bolts are still aligned and no shifting has occurred. If realignment is
necessary, tap the bolt with a wooden block (metal objects will damage the threads).
3.1.9 Allow the concrete to cure for 28 days. Remove form.
3.2 Installation of Tower
3.2.1 If not still on foundation, install T-Base using double hex nut to level the base.
3.2.2 Inspect the mounting tabs on the T-Base assuring they are still straight and undamaged.
3.2.3 Set the tower on the hinged (bottom) side of the T-Base. Align the bottom holes of the tower
mounting tabs with the bottom holes of the T-Base and install hardware. Hand tighten the nuts.
3.2.4 Install Raising Fixture. See Accessories Installation; 3.4.1 Raising Fixture.
3.2.5 Lift the tower to a convenient height and place on saw horse or other support of adequate
strength to install the rotor and antenna.
3.2.6 Install Rotor, Mast Raising Fixture, and Antennas. See Accessories Installation; 3.4.2 Rotor and
3.4.3 Mast Raising Fixture.
3.2.7 Lift the tower into place using the Raising Fixture or alternative (crane, fork lift, etc.)
3.2.8 Install the remaining base bolts.
3.3Set Grouting
3.3.1 Check to assure the tower is plumb.
3.3.2 Use Quickcrete (or equivalent) grout, mixed per directions of bag, to pack the area between the
foundation and the T-Base. Slope the edges away from the T-Base to allow water to drain.

3.5.2 Rotators
3.5.2.1 With the tower in a horizontal position and resting on a saw horse or other support.
Unlock the thrust bearing so pull the top section out far enough for the rotor stops to clear the
top of the second section of the tower.
3.5.2.2 Place the rotor in the tower with the shaft bearing pointing up.
3.5.2.3 Install the rotor mounting plate and bolt the rotor to the mounting plate with the
hardware that came with the rotor.
3.5.2.4 Assemble the rotor mast, mast platform, and mast.
3.5.3 Mast Raising Fixtures
3.5.3.1 Mast raising fixture holes are predrilled on the top plate of the tower (This is only the
case if the MRF was ordered with a tower. If installing a MRF on an older tower, a template
will be needed to drill the holes.) If you are installing a MRF on a tower with a thrust bearing,
you might be required to remove the thrust bearing to install the MRF. See Figure 7 for Thrust
Bearing Diagram.
3.5.3.2 Mount the MRF to the tower. Release the entire length of cable and remove it from the
winch drum. (The small compression brackets that hold the cable to the drum will have to be
removed.)
3.5.3.3 Insert the cable into the guide hole from the bottom and re-attach to the drum.
3.5.3.4 Bolt the eye of the cable through the mast in the predrilled hole, installing a washer on
the both sides of the mast.

3.5.4 Coax Arms
3.5.4.1 Bolt the longest coax arm to the top section as shown in Figure 8. Make sure the
mounting bolt is inserted from the inside of the tower so they cannot catch on the next inner
section during extension and retraction of the tower.
3.5.4.2 Bolt the remaining coax arms in descending lengths at the top of each section, bolted
from the inside out. See Figure 8.

3.5.5 RMC-1000
3.5.5.1 Wire Requirements (not supplied by UST)
3.5.5.1.1 Remote “C” terminal connections use #20 or larger, seven conductors.
3.5.5.1.2 Outdoor relay cabinet “B” terminals to the motor use #14/4 or larger.
3.5.5.1.3 Outdoor relay cabinet “D” terminals to the limit switches, use #18/3 or larger.
3.5.5.2 Remote Control Unit (See Figures 9 and 10 for wiring references)
3.5.5.2.1 Remove power from both remote and relay units.
3.5.5.2.2 Remove cover plates. The remote cover is easily removed by loosening the screws on
each end and removing the two top center screws.
1. Coax cable guides and mounting hardware are an
option that can be supplied with a new tower. Due to
potential shipping damage, the guide arms are removed
prior to shipping and packaged with the tower. Install
the guide arms with the tower in the horizontal position.
2. Install the longest arm on the top (smallest) tower
section. Holes corresponding to those on the arm can be
found at the side of the top of each tower section.
3. Install each successively smaller arm onto the next
lower (larger) tower section. The cable holding loops of
the end of each arm should appear in a nearly vertical
line following installation.
Note: The coax cable guides are standard components
that fit all towers. The appearance of guide ring
misalignment is normal and does not affect function.

3.5.5.2.3 Connect terminals C1, C2, C3, C4, C6, C7, and C8 from the remote to the same
numbered terminal on the outdoor relay unit.
3.5.5.2.4 Replace the cover and screws.
3.5.5.2.5 When all connections have been made and the remote cover replaced, make sure the
remote is off before plugging in. To use the unit, put the center switch to either raising or
lowering position, the right hand switch in the remote position and turn the power switch on. It
may be several seconds before the motor will start to run. This time is set by the delay relays in
the outdoor relay cabinet. If the delay is bypassed, the motor could continue to run in the same
direction when attempting to reverse sections. The tower can be operated at the tower site with
the use of the switch located on the right side of the outdoor relay cabinet. To use this feature,
the remote unit local/remote switch must be in the local position. ALWAYS TURN OFF THE
POWER IN THE REMOTE UNIT TO PREVENT UNAUTHOIZED USE. The center raising/lowering
switch should be in the center position when not in use. Replace the outdoor relay weather
proof cover by pulling out the tab on the inside bottom of the box. A padlock can be installed
and is recommended. ALL ELECTRICAL WIRING AND CONNECTIONS SHOULD BE PERFORMED
BY A LICENSED ELECTRICAL CONTRACTOR. These units are for use with 110 voltages only.
