Limitless™ WDRR Receiver
WARNING
MAKE SURE ALL TOWERS AND MASTS ARE SECURELY GROUNDED, AND ELECTRICAL CABLES
CONNECTED TO ANTENNAS HAVE LIGHTNING ARRESTORS.
This will help prevent fire damage or human injury in case of lightning, static build up, or short circuit within
equipment connected to antenna.
•
The base of the antenna mast or tower must be connected directly to the building protective ground or to
one-or-more approved grounding rods, using 1 AWG ground wire and corrosion-resistant connectors.
•
Refer to the National Electrical Code for grounding details.
•
Lightning arrestors for antenna feed coaxial cables are available from HyperLink Technologies, Inc.
WARNING
If a person comes in contact with electrical power, and cannot move
DO NOT TOUCH THAT PERSON OR RISK ELECTROCUTION
•
Use a non-conductive dry board, stick, or rope to push, pull, or drag them so they no longer are in contact
with electrical power.
•
Once they are no longer contacting electrical power, administer CPR if certified, and make sure
emergency medical aid has been requested.
8.3.3 Antenna Connection, Styles, and Mounting Options
WARNING
RF EXPOSURE
To satisfy FCC RF exposure requirements for mobile transmitting devices, a separation distance of 20 cm
[7.87 in] or more should be maintained between the antenna of this device and persons during device
operation. To ensure compliance, operation at closer than this distance is not recommended. The antenna
used for this transmission must not be co-located in conjunction with any other antenna or transmitter.
Failure to comply with these instructions could result in death or serious injury.
CAUTION
WDRR
Power to the
should not be applied during installation of an antenna as damage could occur to the
WDRR
electronics.
8.3.3.1 Antenna Connection
Physical connection of the antenna to the WDRR is accomplished by using mating RP-SMA connectors: plug and
jack. Integral-mount antennas have an RP-SMA plug that connects directly to the WDRR RP-SMA jack. The remote
mount antenna uses a cable with a RP-SMA plug that connects directly to the WDRR RP-SMA jack allowing the
antenna to be remotely mounted away from the WDRR. Mounting options are based on user preference,
communication agency approvals, WDRR mounting location, and obstacles as discussed in Section 8.3.1.
An integral or remote mount antenna can be easily mounted by threading the mating RP-SMA plug of the
antenna to the WDRR's RP-SMA jack. Reference section 8.4.1 for further details on extra environmental protection
of RP-SMA connections. Tighten the RP-SMA connection until finger tight. See Figures 11 and 12.
