Mounting And Orientation - Lectrosonics SRC-941 Quick Start Manual

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 regardless of the orientation of the receiver.
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 hori-
zontal position with the whips oriented vertically.
Fig. 3 depicts the receiver and antenna whips oriented horizontally, which
places the null of the receiver antenna 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 dia-
grams, 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.
