Horizontal installation on a bench for long time may cause damage to the Repeater

due to over-heating.

The following criteria should be considered when selecting the Repeater installation site

location:

• Application type – indoor or outdoor

• Distance from antenna site - It is recommended that the installation location be as

close as possible to the antenna site in order to maintain the cable loss to a

minimum.

• General surroundings and accessibility of location

• In outdoor applications it is recommended to install a cabinet or a shielding sunroof

for further protection against weather wear.

• Use a suitable mounting surface, such as a flat back rigid wall.

• The Repeater is convection cooled so airflow and alternation should be possible.

eye level.

• Ensure that adequate airflow and ventilation within the rack and around the installed

components so that the safety of the equipment is not compromised.
