Antenna Options
Before installing the MiniBox-4, you should also
consider antenna options (if you are using RF analog or
digital transmission). You have the choice of using one
or two patch antennas.
Using both patch antennas with the supplied splitter
will provide the largest radiation pattern but at a
lower gain. Using one antenna will make the radiation
pattern directional, but will typically double the gain,
which will increase the signal range in that direction.
To configure for one antenna, disconnect the coax
from the transmitter at the bottom of the splitter and
connect the double-female adapter in its place. Connect
the cable from the desired active antenna to the
adapter. See illustration top right.
To configure for two antennas, disconnect the coax
from the transmitter at the double-female adapter and
connect the splitter (input) in its place. Connect the
cables from both antennas to the splitter (outputs). See
illustration bottom right.
NOTE: Do NOT remove antenna connections
with device powered ON!

2. Drill a pilot hole at the pencil mark for a mounting screw. Make sure
the wall is composed of solid, strong material such as wood or metal,
Select a fastener that will support at least 30 pounds.
3. Install the screw but leave enough of the shank exposed (1-1/4”
minimum) to hang the MiniBox-4 on.
4. Hang the MiniBox-4 as shown (left).
5. With the MiniBox-4 plumb and level, drill and mount a second screw
in the bottom mounting hole.
6. Tighten the top screw.
NOTE: Do NOT overtighten the mounting screws. Tighten enough to snug
the wall mount bracket to the wall. Overtightening may bend or damage the
mounting plate.
Pole-Mounting the MiniBox-4
To pole-mount the MiniBox-4, complete the following steps:
1. Use the Wall Mounting Scheme steps 1-4 (left) to hang the MiniBox-4
on the pole. Alternatively, a helper can hold the MiniBox-4 in place
for step 2 below. The back of the MiniBox-4 features a self-centering
bracket.
2. Using a band-clamp (provided), secure the top of the MiniBox-4 to the
pole as shown (right).
3. Using a band-clamp (provided), secure the bottom of the MiniBox-4 to
the pole in the same fashion.
