Modems and boards Installation: Principles and cautions
_ The radio environment should be closely studied prior to any installation in
order to determine whether and where the installation will be optimal.
_ The modems should be located as high and as free as possible so that a line
of sight propagation is established between modems to achieve a better radio
link.
_ The modem should not be surrounded by metallic masses because of the
disturbances caused by a reflection phenomena.
_ The electrical disturbances can come from various sources and should be
avoided:
_ Engines
_ High current devices
_ Power relays
_ Transformers
_ Etc
…
_ Vibrations and/or shocks can also be source of disturbances. It is therefore
advised to mount the modems on silent-blocks in order to stabilize it whenever
necessary.
