1.0 Introduction The ETS-Lindgren Model 2070B (non bore sight) and Model 2071B (bore sight) Antenna Positioning Towers are portable mast and platform systems designed for use in EMI compliance testing at elevations from one to four meters above the ground level. The mast, carrier, boom, platform, drive belts, and guying system are non-conductive and non-magnetic. The carrier is raised and lowered by a fractional horsepower electric motor with a gear reducer and electric brake.
Fiber optic limit switches mechanically limit the travel of the carrier. The upper limit is at a fixed location to stop the carrier at its maximum height. The lower limit is adjustable to fit test requirements. In addition, the Model 2090 Series Multi-Device Controller allows programming two upper and two lower limit settings. For more information on the Model 2090, see page 11. The Model 2070B/2071B features centerline air polarization, which enhances measurement accuracy.

Assembly Steps DO NOT DAMAGE FIBER OPTIC CABLES During assembly do not pinch or damage the fiber optic cables. When inserting the mast into the lower mast section on the base, do not pinch or damage the fiber optic cables. When installing the mast locking pin, do not pinch or damage the fiber optic cables. For illustrative purposes, the photos in this section show the Model 2070B/2071B partially and/or fully assembled. Follow the steps to assemble the Model 2070B/2071B.
1. Place the base of the Model 2070B/2071B in the chamber or other designated installation location. 2. Place the mast horizontally onto an elevated, stable surface, such as sawhorses. 3. Carefully slide the carrier unit onto the mast. Orient the carrier so that when the mast is inserted into the base: The carrier belt clamp will be directly over the drive pulley on the motor base; and The carrier belt clamp is in line with the mast pulley.
4. Install the drive belt with the teeth facing each other. Feed the belt up through the outer clamp slot on the carrier belt clamp, around the mast pulley, and back down so both ends of the belt can be accessed when the tower is vertical. Leave approximately 0.5 m (1.5 ft) on both ends of the belt. Temporarily tape the two ends together so the drive belt does not slide out of the pulley while the mast is being raised.
5. Remove the mast locking pin and pivot the lower mast section down and horizontal to the floor. 6. With the mast and lower mast section in horizontal position, insert the mast into the lower mast section, aligning the pulley at the top of the mast with the pulley on the motor. 7. Raise the mast and lower mast section to a vertical position and re-insert the mast locking pin. 8.
9. Attaching the boom: MODEL 2070B ONLY TIP | Run the antenna cables through the boom sections while assembling the boom. Be careful not to pinch or damage the cables. Attached to one end of the boom unit is a cable guide that reduces the stress on the antenna feed cable; this cable guide must be removed to install the boom. 24 Remove the bolts that hold the cable guide in place, and set the unit to the side.
MODEL 2071B ONLY TIP | Run the antenna cables through the boom sections while assembling the boom. Be careful not to pinch or damage the cables. The boom assembly ships with the antenna mount section separated from the cable guide section. To assemble and install the boom: Install cable guide section: Loosen the four 1/2–13 bolts, and then slide the cable guide section into the boom slot, making sure that the cable routing opening is facing up. Re-tighten the four bolts.
10. 26 Block the carrier so that the reference point on the largest antenna you use will be set at one meter. Place a piece of wood under the carrier to support it at this height.
11. Remove the guard plate located behind the motor base enclosure. Rotate the four thumbscrews to loosen the guard plate, remove the guard pin, and then lift the plate to remove it.
12. 28 Remove spring tension by carefully pulling back the belt tension idler on the motor base. While holding back the belt tension idler, insert the guard pin through the hole on the back of the guard plate enclosure to secure it in place.
13. Continue routing the drive belt down and around the motor pulley and up through the inner clamp slot on the carrier belt clamp (see photo of inner clamp slot on page 22) until approximately 0.5 m (1.5 ft) of belt is through the clamp. Remove the tape you placed on the drive belt in step 4.
14. 30 Hand-tighten the drive belt: Loosen the four bolts on the carrier belt clamp. Grasp both ends of the drive belt and pull them in opposite directions until the belt is as taut as possible. Re-tighten the four bolts on the carrier belt clamp.
15. Install the upper clamp block (the one with a single groove etched in the side) to lock one end of the drive belt in place. The upper clamp block is comprised of three parts; assemble the parts as follows on top of the carrier belt clamp: Place the flat plate between the drive belt and drive belt end. Place the smooth block on the outside of the drive belt with the drive belt between the smooth block and the flat plate.
16. Install the lower clamp block (the one with two grooves etched in the side) to lock one end of the drive belt in place. Like the upper clamp block, the lower clamp block is comprised of three parts. Assemble it like the upper clamp block, but place the parts below the carrier belt clamp. Tighten the two bolts on the lower clamp block. 17. Loosen the four bolts on the carrier belt clamp.
18. Using a 3/16-in Allen wrench (hex key), tension the drive belt with approximately 100–150 lb of pull on each end. Insert the Allen wrench into the hole in the front of the upper clamp block, and then into the hole in the lower clamp block.
19. 34 Re-tighten the four bolts on the carrier belt clamp using 11 N-m (100 in-lb) torque. Insert the four jam nuts and use approximately 7 N-m (60 in-lb) on the jam nuts.
20. Remove the guard plate pin from the back of the guard plate enclosure and replace the guard plate. Tighten the four thumbscrews and insert the pin in the front of the guard plate. The fiber optic limit switch is designed to stop the boom from traveling beyond a safe distance and causing damage to the Model 2070B/2071B. You must implement additional safeguards to prevent damage to any antenna installed on the Model 2070B/2071B.
21. To install the fiber optic limit switch: With the carrier at 1 meter, clamp the fiber optic limit switch assembly to the mast. Slide the fiber optic limit switch to the 1 meter position. 22. Carefully move the belt tension idler into place against the drive belt and re-install the spring if it was removed. The tension idler should be free on its pivot and the spring should force it against the belt. 23.
Air Polarization Assembly The automated air polarization assembly includes variable speed polarization cycling using flow control valves. The air cylinder is made of non-conductive material and will polarize the largest antenna recommended for the tower. The polarization speed range o o is 3 to 30 per second. An air supply of 414-551 kPa (60-80 psi) is needed for this feature. It is important to have clean and dry air; so we recommend the use of a 40 micron filter in close proximity to the motor base.
