Antenna Mounting And Orientation - Lectrosonics DCR822 Instruction Manual

Tx Bat Icon
Choose between Bar, Volt or Time. Use MENU/SEL to
select the channel and the UP and DOWN buttons to
change values.
AutoOn
Press the UP or DOWN buttons to enable or disable the
auto power on function.
Edit Names
Edit channel names to easily identify channels on the
receiver home screens or identify different DCR822
receivers in a rack. Press MENU/SEL to move the cur-
sor, and press the UP or DOWN buttons to change the
numbers and letters at that cursor location. Press the
PWR/BACK button to save your changes.
Date & Time
Allows setting of calendar date in Year, Month and Day,
and time in 24 hour clock, with minutes and seconds.
This information is then placed in the meta data header
on any .WAV files recorded onto the microSD card.
Locale
The locale should be chosen based on the region
where the receiver is being used. There are two options
available:
- NA: (default setting) represents the North Ameri-
can locale and prevents operation in the
Astronomical Band (from 608 to 614 MHz). It allows
tuning from 470.100 up to 607.950 MHz.
- EU: represents the European locale, and has un-
restricted operation over the entire band of the de
vice: 470.100 up to 614.375 MHz.
Default
This setting restores the unit to factory settings.
About
Displays general information about the DCR822,
including serial number and hardware, firmware and
FPGA versions.
Antenna Mounting and
Orientation
A variety of accessories are available to enable vari-
ous antenna 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 regard-
less 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 horizontal
Rio Rancho, NM
Dual Channel Digital Receiver
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.
