CommScope ASP7A Instruction Sheet

27-2200-3 Revision C,
High Band Ground Plane Antenna
ASP7A
GENERALINFORMATION
This antenna is supplied to operate satisfactorily within the
frequency range(s) specified on the carton label. Some mod-
els require cutting of the radiator and/or radials in accordance
with the charts located on page 2. If the antenna is to be used
over a range of frequencies, the element lengths should be
chosen for mid-range or favor the element lengths for the most
used, or the frequency requiring the greatest range.

INSTALLATION INSTRUCTIONS

1. Select antenna location and route cable from set to an-
tenna.
2. Loosen mounting nut and assemble radials to hub as
shown in Figure 1. Tighten jam nuts and lockwashers
against hub to secure the radials. Retighten mounting
nut.
3. Connect cable to antenna (accepts PL-259).
Some models are supplied with cable and connector for
the antenna end. Radio end connector is not supplied.
4. Mount antenna onto 1/2" to 3/4" pipe, or up to 1-3/8" O.D.
tubing (not supplied) with "U" bolt, lockwashers and hex
nuts provided.
5. Secure cable to mounting pipe with strap or plastic tape
to avoid strain on cable connections.
The use of a PTFE or similar lubricant on the
threaded portions of the antenna, prior to assem-
bly, will protect from weather and ease future dis-
assembly.
