19. Installing and cabling
19.1. Location
TFA units shall be installed as close as possible to the radiating antennas, so as to
minimise coaxial cable length and reduce downlink power loss and uplink noise
figure.
However, the units should be installed no closer than 2.5 m to the closest mobiles
approach to avoid blocking. If remote units need to be installed very close to
where mobiles are, the internal variable attenuator should be used.
The TFA is intended to be installed on walls, false ceilings or other flat surfaces. A
mounting bracket is available for easy mounting.
Proper installation of the TFA is required for optimal performance. Take care to
install the TFAs "warm side out" as indicated in Fig. 14 The positioning of the unit
and the cables is important so as to avoid accidental damage.
