Introduction | 7
1.0 Introduction
The ETS-Lindgren Model 1052
Antenna Tower Positioning
System is designed for portable
antenna positioning in EMC
compliance testing.
A hand winch and pulley drive
system elevates the antenna
carrier from one to four meters.
Maximum carrier load capacity
is 11.3 kg (24.91 lb) on the tip of
the cross boom. For loads
measured on the center of the
cross boom, the capacity is
22.7 kg (50.04 lb).
The mast is constructed of a high density fiberglass reinforced polymer with a
high degree of immunity to structural deterioration from environmental elements.
The base is an aluminum four-leg design for maximum support and portability.
The design of the Model 1052 allows easy assembly and usage.

safety information in the ETS-Lindgren
Product Information Bulletin included with your
shipment.
Prior to assembly and operation of the Model 1052 Antenna Tower
Positioning System, read Operation on page 21.
1. Attach lower mast section to base assembly—Install the lower mast onto
the center post of the base assembly, aligning the markers.

14 | Assembly Instructions
The rope clamp is located on a wire (as shown) for shipping purposes
only. During step 6 of the assembly instructions you will move the rope
clamp to the rope.
2. Attach winch assembly to lower mast section
•Install the winch assembly onto the lower mast with the crank side of the
winch aligned with the marker on mast. Place the crank on either side of
the mast, as desired.

Assembly Instructions | 15
•Secure winch with winch lock pin by sliding the pin through the winch and
mast.

16 | Assembly Instructions
3. Slide carrier assembly onto lower mast.
•Carefully place the mast and base assembly onto the side.
•Slide the carrier assembly over the lower mast.
•The carrier assembly and boom collar/brackets should face away from the
winch. The long side of the carrier assembly should face upward.

Assembly Instructions | 17
4. Install upper mast section—With
the pulley at the top, insert the
upper mast into the lower mast, and
align the markers.
5. Thread winch rope from winch,
through pulley, and down the
other side to the carrier.
•Remove the clevis pin at the top
of the upper mast.
•Unwind the winch rope to the top
of mast and place it over the
pulley.
•Secure the rope in the pulley
groove with the clevis pin.

18 | Assembly Instructions
•Continue to unwind rope until there is enough rope to reach the winch.
•Secure the rope with a loop to the carrier assembly at the boom brackets.
Use the rope clamp to secure.

Assembly Instructions | 19
6. Move rope clamp from shipping wire to rope.
•Remove the four bolts from the rope clamp to separate the two pieces.
•About two inches above where the rope is secured at the boom brackets,
place one piece of the rope clamp on each side of the rope.
•To clamp the rope, re-attach the two pieces with the four bolts.
7. Attach boom—Insert the boom through the boom brackets on the carrier
with the cable guide oriented towards the back.

20 | Assembly Instructions
8. Install extension legs.
•Position the carrier at the winch assembly.
•Raise the entire unit until it is in an upright position, resting on the base.
•Install the extension legs into the base with each leg oriented so the
pin hole is nearest to the bottom side of the leg.
•Secure each extension leg with a lock pin.
•Use thumbscrews to make vertical adjustments to legs.
9. Thread cable through cable guide—Insert the feed cable for the antenna
into the cable guide to reduce stress on the cable and antenna connector.
Mount an antenna to the boom by threading the mounting knobs up through the
holes in the boom and into the mounting receptacle on the antenna.
