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.
