Connecting antennas
Antennas play critical role in the setup and operation of wireless mesh systems.
Depending upon the results of the site survey and the requirements of the installed
environment, proper antenna type (omni-directional vs. directional, low-gain vs. high
gains, and so on) must be determined.
The various types of antennas offered with FDAP enhances the field instruments'
wireless coverage in multi-path environment.
After all the antennas are installed, the connections must be sealed to protect them from
the external environment.
Outdoor protection kit
If any portion of the FDAP (enclosure, antennas, cables, and so on.) is to be mounted
outdoors, it is recommended that you use the Outdoor Protection Kit with the installation.
This kit contains lightning arrestors and ground cables designed for installation with
FDAP.
ATTENTION
If the system is mounted outdoors where CE Mark certification is required,
use of the Outdoor Protection Kit (or equivalent) is mandatory.
An outdoor protection kit must be used for preventing the lightning damage, when the
FDAP is mounted outdoors. The outdoor protection kit contains the following items.
Three lengths (10, 12 and 18-inches) of 10AWG wire with #8 ring terminal on one
end and a #10 ring terminal on the other end.
Two lightning arrestors, with Type N Male-to-Female, or two Reverse Polarity Type
N (RPN) Male-to-Female connectors for the mesh and AP radio antennas.
One Lightning arrestor, Type N Male-to-Female connectors for Field I/O radio
antenna.
Installing lighting arrestor
A lightning arrestor must be installed between the antenna and the FDAP antenna
connector when the unit is installed outdoors.
Mounting the FDAP
The assembled FDAP, complete with antennas and lightning arrestors (if required), is
now ready to be mounted in its site location.
