Summary



Flexi BTSA BTS built with modules

Cabinets are not needed with a module-based BTS

Modules are in weather-proof casings with front and back covers (IP55)

Casings allow removal of the modules from the stack

Temperature range: -35C +50C; temporarily +55 C

Modules can be installed in cabinets

Casings are not used in cabinet installations

Modules are small and light-weight

One person can transport and install BTS without using lifting equipment
