Mounting and Orientation
A variety of accessories are available to enable various
mounting options. For maximum operating range, the
antennas should be vertical and above the camera and
other equipment. The AMJ Rev. A antenna is jointed so
the whips can be oriented vertically.
Mount the receiver
so that the antennas
extend into clear air and
are oriented vertically
to provide a circular,
horizontal coverage
pattern
Do not mount the receiver so the
antennas will be next to another piece of
equipment nor oriented horizontally
The receiver provides stand-
alone operation with the battery
sled adapter and mounting
sleeve. It can be mounted in
any position with Velcro, or in
horizontal and vertical positions
using the mounting foot, or
mounted directly onto a 1/4-20
threaded stud on a tripod.
The diagrams below depict typical orientations of
transmitter and receiver antennas in field production
and how the RF signal transfer is affected. Maximum
sensitivity is perpendicular to the whip, so an ideal
setup is shown in Fig. 1 and Fig. 2 where the receiver is
mounted in either a vertical or horizontal position with
the whips oriented vertically.
Fig. 3 depicts the receiver and antenna whips oriented
horizontally, which places the null of the receiver an-
tenna pattern pointing toward the transmitter. The result,
of course, is a weak signal entering the receiver.
Fig. 4 depicts the worst setup where the nulls in both
receiver and transmitter patterns face one another.
The transmitter antenna whips can point upward as
shown in these diagrams, but they will work just as well
with the whip pointing downward. Mount the transmitter
so that the whip is vertical and not in direct contact with
the wearer’s body or metallic objects in clothing and
costuming.
