• Liquid thread locker

• Liquid-tight ﬂexible electrical conduit (UL listed)

• Straight, insulated liquid-tight, 1-in electrical conduit connector

• Concrete (if needed)

• Test tag and reader to verify tag operation

Installation Procedures

This section provides procedures for the following tasks:

• Preparing the antenna site

• Securing the antenna hardware connections

• Fastening the antenna to the trackbed

Note: To install the AA3233 Antenna correctly, follow these procedures in the order in which they

are presented. The AA3233-002 has an integrated check tag. Instructions that pertain only to the

installation of the check tag will be be noted.

Preparing Antenna Site

Before you install the antenna, use the following instructions to prepare the site where the antenna is to

be installed.

1. Identify the approximate antenna location on the track bed. The location should be centered

between the rails. Mark parallel and perpendicular centerlines on the track bed (Figure 1).

Installation Guide

Note: Remove the template from the concrete base before installing the antenna.

2. Ensure that area where the antenna will be mounted in the railroad trackbed is clear of any metal

obstruction other than the rails as shown in Figure 2.

3. Check that the track bed is suciently level by laying a 20 in (50 cm) straight edge on the track

bed perpendicular to the rails. This straight edge should align with the centerline of the two

isolators (refer to Figure 1 for location of isolator) located near the connector and the centerline of

the end isolator. Measure the distance from the track bed to the bottom of the straight edge. The

track bed should not dip more than 1.75 in (4.42 cm) below the straight edge at a distance of 5-in

(12.7 cm) from the centerline of foot block #3. Additionally, the track bed surface should be smooth

(within 0.5 in) over the lengths of the 15-in (38.1 cm) and 5 in (12.7 cm) segments (Figure 3).

Figure 2 Metal-free Zone Around Antenna

Installation Guide

4. Place the template on top of the intersecting centerlines. Center the antenna template — within

2in (5.1 cm) of track centerline — on the line that is parallel to the rails, then align it with the line

drawn perpendicular to the rails (within 15 degrees).

5. If the track bed is out of speciﬁcation from the measurements provided in Step 4of this section,

grout the track bed base with up to 0.5 in (1.3 cm) of grout replacement to bring it to speciﬁcation.

Allow sucient time for the grout to cure before proceeding to the next step. Redraw the track bed

centerlines if necessary.

Note: If track bed cannot be brought into the speciﬁcation stated in Step 3, change antenna

location.

6. When the track bed base is within the requirements of Step 3, stretch the template across any

“valley” (as shown in Figure 3) to get the proper center-to-center spacing between the foot blocks.

Use the template to mark and drill six 0.375 in (0.95 cm) wide x 3 in (7.6 cm) deep holes in the

concrete. Check that the template centerlines are aligned with the track bed centerlines (see Step

3of this section).

7. Clear the concrete dust from the wedge anchor holes.

Securing Antenna Hardware Connections

After you have prepared the site as speciﬁed in “Preparing Antenna Site”, follow the steps below to

secure the hardware connections.

1. Place the antenna upside down on its cover (radome facing down) on top of the template to

protect the cover from being scratched.

2. Remove the locking nut and plastic washer from the conduit connector. Insert connector through

the 1-in conduit connector onto the end of the connector enclosure cover. Replace the washer

and nut and tighten the conduit enclosure connector nut to torque of 28 ft-lb (Figure 4).

3. Insert the ﬂexible conduit into the 1-in conduit connector, and tighten the conduit connector nut

to torque of 12 ft-lb (Figure 4). The ﬂexible conduit is now secured to the connector enclosure

cover.

4. Insert the antenna cable and check tag cable (AA3233-002 only) from the reader into the ﬂexible

conduit. Slide the cable(s) through the ﬂexible conduit (Figure 4).

5. Pull the antenna cable through the hole in the connector enclosure cover and out of the

connector enclosure cover until the cable end extends approximately 1 ft (30.5 cm) beyond the

cover.

6. Attach the antenna cable to the type N connector located on the antenna baseplate by ﬁrst

tightening the conduit locknut securely by hand and then using the soft-jaw pliers to tighten the

locknut an additional one-half turn. Attach the antenna cable to the reader.

7. (AA3233-003 only) Place the antenna in the right-side up (radome facing up) position and test the

antenna by reading a tag held about 18 in (45 cm) over the antenna.

8. (AA3233-002 only) Attach the check tag cable to the check tag connector located on the

antenna baseplate by inserting then twisting the connector ⁄ turn to right to lock the connector.

Attach the check tag cable to the reader.

• Check that the antenna is working properly by reading a check tag. (This step assumes that

the installer is using and is familiar with an AI1200 Reader.)

Installation Guide

• Ensure that the reader is switched on and in data mode(#00). Enter command #8110 to enable

the check tag.

Reader response: #============= 00

• Switch o reader.

9. Turn the antenna upside down on top of the template to protect the cover from being scratched.

Attach the connector enclosure cover to the connector base plate using twelve 10-32 x .188-in

shoulder screws (Figure 5).

10. Apply liquid thread locker to all screw threads. Tighten each screw until its shoulder bottoms out

against the baseplate and secure to torque of 20 in-lb.

Fastening Antenna to Track Bed

After you have secured the antenna connections as speciﬁed in “Securing Antenna Hardware

Connections”, follow the steps below to fasten the antenna to the track bed.

1. Lift the antenna from on top of the template.

2. Remove the template from the antenna location and place antenna right side up (radome facing

up) on template.

3. Assemble the washer and nut on the wedge anchor stud so that the nut rests below the

chamfered head.
