Wall Antenna

Prior to installing the antenna, the site, antenna location, cable route, and all other details should have been planned.

S

Installation procedures are to follow local company procedures and the Installation Job Specification.

For best results, choose a wall facing the equator (facing south in the northern hemisphere, facing north in the southern hemisphere), and with the fewest obstructions of the sky.

To mount the antenna through the wall, refer to Figure 21 and follow Procedure E.

Procedure E. Wall Antenna Installation

Step Action

Prerequisite:

Observe all guidelines, considerations, Dangers, Warnings, Cautions, and Notes in the

Engineering and Ordering chapter.

Symmetricom Parts:

• Wall Antenna (990-72050-95 with 6’ antenna cable or 990-72050-99 with 19’ antenna cable)

• Wall Antenna Indoor Lightning Suppressor Kit (093-72050-94) (optional)

• Wall Antenna Outdoor Lightning Suppressor Kit (093-72050-93) (optional)

• A length of RG-59/U plenum-rated coaxial cable (060-72010-xx), or

• A length of Mini RG-59/U plenum-rated coaxial cable (060-72050-xx)

User-Supplied Materials:

• Ladder, or safe method of reaching the antenna location on the exterior wall

• Drill with bits of appropriate size and type to make pilot holes for the antenna mounting bracket screws, and to make a hole through the wall for the antenna cable

• Two screws of appropriate size and type to attach the antenna mounting bracket to an exterior wall

• Screwdriver

• Electrically conductive antioxidant compound (Kopr-Shield or equivalent) to coat exposed connections to prevent oxidation

• Fire-stopping material to seal the hole in the wall

• GPS handheld receiver, personal computer with GPS location software, or other method of determining latitude, longitude, and altitude

1 Attach the IF downconverter (Figure 20) inside the building to a suitable wall or other structure. Be sure the distance along the cable route between the IF converter and the antenna is no more than 6 ft. or 19 ft depending on wall antenna length used. Include allowances for the drip loop and local company procedures for cable routing.

2 Use Figure 22 to determine the spacing of the 2 holes for mounting the bracket, and the distance to the hole for passing the cable into the building.

3 Drill a 25/64-inch (0.390625-inch) hole in the wall for the antenna cable. The diameter of the hole should be larger than the outer diameter of the SMA connector on the antenna cable, which will pass through the hole from the antenna to the inside of the building.

Procedure E. Wall Antenna Installation (cont’d)

Step Action

4 Drill two pilot holes for the user-supplied screws or bolts that attach the mounting bracket to the outside wall.

5 Using two screws or bolts, mount the antenna bracket assembly to the outside wall.

6 Place the magnetic side of the antenna on the outside of the mounting bracket.

7 Push the SMA connector of the antenna cable through the hole drilled in the wall in Step 3. Be sure the antenna cable forms a drip loop between the antenna and the cable entry into the building (Figure 23).

8 Route the antenna cable to the antenna side of the IF converter and connect the cable.

9 Connect a cable to the TimeSource 3500 shelf side of the IF converter and route the cable to the shelf location.

10 Secure the cable using local company procedures.

11 Install fire-stopping material in all holes opened in the roof and/or walls during this procedure.

12 Check all connections for tightness to prevent intermittent operation.

13 If no optional Lightning Suppressors are to be installed, the Wall Antenna

Installation in Procedure E is completed here.

14 If the optional Wall Antenna Indoor Lighting Suppressor Kit (093-72050-94) is not required, then go to Step 23. Otherwise, proceed with the next step.

15 Mount the indoor lightning suppressor mounting bracket to the inside wall.

16 Mount and secure the lightning suppressor in the lightning suppressor mounting bracket as shown in Step 17.

18 If the lightning suppressor was not mounted directly to a valid earth ground, crimp a length of 6 AWG (4.115 mm) ground cable to the two-hole terminal, slide the terminal over two of the three threaded posts on the lightning suppressor mounting plate, and attach the terminal to the mounting plate with two KEPS nuts.

Use the two posts that allow the least bending of the 6 AWG (4.115 mm) ground cable.

19 Attach the other end of the cable to a valid earth ground.

20 Route the wall antenna cable to the antenna side of the IF converter and connect the cable.

21 Connect the IF converter to the lightning suppressor using the two-foot RG-59 cable provided.

22 Connect the user provided RG-59 cable from the lightning suppressor to the

TimeSource 3500 shelf.

24 Mount the outdoor lightning suppressor mounting bracket to the outside wall shown in Figure 24.

25 Mount and secure the lightning suppressor in the lightning suppressor mounting bracket as shown in Step 26.

Use the two posts that allow the least bending of the 6 AWG (4.115 mm) ground cable.

28 Attach the other end of the cable to a valid earth ground. Attaching to an earth ground located outside the building is the most desirable.
