ACTIVE CELL ANTENNA
The ACAs physical dimensions are;
24.5 in. (L) X 13.02in. (W) X 3.31 in. (H)
62.23 cm.(L) X 33.07 cm. (W) X 8.41 cm (H)
These devices have 2 LED indicators at their
outside edge, one red and one green. When lit,
the green LED indicator signifies that d-c
power is applied.
A single BNC connector is located at the top
center of the assembly. Depending on
customer requirements, some ACAs are
delivered with dust- and moisture-resistant
covers. At least 5 inches should be allowed for
clearance of the ACA i- f cable.

The ACA requires 15-volt d-c power, which is
supplied through the RG-58 i-f cable shield and
center conductor. Suitable filtering in the ACA
isolates d-c from the radio-frequency signal
and the r-f signal from the d-c power bus.
Installation Instruction Guide
Mounting an ACA:
The optimum mounting height for an ACA is from
12 to 15 feet above the floor. ACAs must always
be installed with an unobstructed free area of at
least two (2) feet beneath it. In all cases, the
ACA should be at a minimum height of eight
(8) feet so long as a minimum of (8) inches
separation is maintained between the ACA
and any human contact during operation.
There are two primary methods of mounting an
ACA in order to remain within that height range.
One is for the suspended ceiling that is
constructed of a steel frame with tile inserts and
is within the height range. The other is designed
for an open ceiling or a suspended ceiling that is
higher than 15 feet.
The package your ACA was delivered in has a
plastic packet that contains two (2) T-bar clips
and two (2) S-hooks. The T-bar clips will snap
onto the T-bars of the suspended ceiling (as
shown in Figure 1), providing a loop for the SÂhook which will attach to the ACA hanging straps.

ACA mounting
During installation, check that both ends of all
coaxial cables are marked.
Taking aisle direction into account (Figure 1),
mark the ceiling-tile frame opposite the place
where the coaxial cable feeds through the ceiling
tile. Measure 5-inches in both direction on the
ceiling frame and snap a T-bar clip in place (5)on
the ceiling tile T-bar frame at each measured
spot.
MCC to ACA cable connections should be made
as each ACA is installed.
Make sure that the cable from the MCC does not
bind on the hole through the ceiling tiles (item 3 of
Figure 1), also make sure that the stress relief on
the cable to the MCC does not exert any pressure
on the ACA which might disrupt its level position.
You should check the level of the ACA after it is
mounted to insure that it is level both parall el wit h
and perpendicular to the aisle.
The antenna being out of level will dramatically
affect the RF energy transmission and thereby
the efficiency of the entire system.
Feed one end of an S hook (Figure 1) through
one of the T-bar clip eyes and the other end of
the same S hook through the ACA bracket eye.
Do the same with the second T-bar clip and the
other ACA bracket eye.
