6.2 Preferred installation sites
All buildings and constructions have a certain movement of their own. It’s
determined by the structure and material of the building. Metal structures can shift or
twist due to temperature changes. Wooden construction can expand or shrink with
any changes in humidity. Give preference to concrete or brick buildings. On the
other hand high structures like towers, skyscrapers or poles are always subject to
movement. Mount the support frame to walls of the building or near corners, as they
are the most stable spots. Use appropriate consoles for wall mounting. If a stand is
used on the top of
building, secure it directly to the ceiling or to the concrete cornice wherever is
possible. Do not fix stands to insulating materials as they can slowly sink under the
weight of the unit and with temperature changes. Big chimneys and smokestacks
may look stable, but as their inner temperature varies they can also move. Vibration
caused by heavy traffic, trains and elevators etc. may slowly move the system out of
its specified direction. Another important consideration is to provide enough space
for alignment and to have the potential for future maintenance. Consider that the
support frame is usually heavy, so the selected spot should be easily accessible.
Preferred installation
sites Pay attention to Avoid (*)
Concrete wall Behind window Soft materials
Brick wall Old constructs Chimneys
Microwave towers Wooden constructs
Metal masts or Frames
Hidden heat isolations,
like Styrofoam
(*)
In cases where installations are listed under “AVOID” cannot be avoided than special mounting
accessories to be designed and special installations must be used.
It is not only the building that has to be solid, but the support structure too. Antenna
poles and security camera holders are not suitable for the
GeoDesy-FSO units.
