Filters and lightning protectors
If a radio modem system is installed in an environment that contains high-power transmitters or
sources of radio frequency interference, it is highly recommendable to insert suitable filters
between each radio modem and its antenna. If a station is installed to a location exposed to
lightning, it is recommended to insert a lightning protector to the feed-line outside the protected
zone. SATEL Customer Support can give guidance in the selection of suitable filters or
protectors.
