RACK MOUNTING OPTIONS
RACK MOUNTING THE PA ANTENNA COMBINER
WARNING: Do not torque the screws too tightly, or the chassis may be damaged.
Single Unit
1. Remove the screws and washers from each side of the unit.
2. Align the supplied rackmount brackets over the holes.
3. Using the screws and washers from step 1, fasten the rackmount brackets.
Dual–Mounted Units
1. Remove the screws and washers on each side of both units.
2. Placing the two units side-by-side, screw the link bars to the inside panels of each unit. The units are designed
so that the link bar on the right unit will fit directly on top of the link bar of the left unit (facing front). Use two of
the screws and washers from step 1 per link bar to fasten them.
3. Align the rackmount brackets on the outside panels of the units and fasten using four of the screws and wash-
ers from step 1.

Mounting in an Equipment Rack
SINGLE MOUNT DUAL MOUNT
1. Insert the unit(s) into a 19-inch equipment rack.
2. Fasten the unit(s) to the rack using all four of the supplied screws.
FRONT MOUNTING THE ANTENNA
The PA Antenna Combiner comes equipped so the antenna can be front-mounted. Front-mounting prevents antenna cables from be-
coming entangled and greatly minimizes RF interference from other cables. When a unit is located in a rack, antennas should be either
front- or remote-mounted.
1. Insert the bulkhead adapter through
the hole of either mounting bracket,
and secure it from the back using the
supplied hardware.
2. Connect the transmitter antenna out-
put to the bulkhead adapter with the
supplied RF cable.
3. Install the antenna on the bulkhead
adapter.
NOTE: The PA715 antenna, which comes supplied with the PSM transmitters, cannot be remote mounted.
Use a PA705 antenna for remote mounting.
