ADAM-4550 User's Manual 13
2.8 Antenna Installation
Indoor communication distance is about 300 to
550 ft. using a standard 2 dB antenna. Howev-
er, actual distance depends on environmental
conditions as well as antenna type and position-
ing.
Longer communication distances can be
achieved by using an antenna with a higher gain.
A table of communication ranges as a function
of differing combinations of antennas (at the
source and receiving ends) is displayed below.
Note : 1. While using directional antennas, care
should be taken to install and adjust the anten-
nas direction according to the instructions of
the antenna’s manufacturer. Please see the
example specification for an external 24 dBi an-
tenna at appendix A.
2. A user’s license may be required to use a
directional antenna. Please consult your local
authority for local regulations.
3. We strongly recommend that you install
ADAM-4550 as near as possible to its antenna.
Where the antenna has to be located at a dis-
tance from the ADAM, special RF cable is re-
quired. Please see the example cable connec-
tion arrangement in appendix B.
4. Omnidirectional antennas should be used
when the ADAM-4550 communicates with more
than one other ADAM-4550 unit located in dif-
ferent directions.
