TMA
The Tower Mounted Amplifier (TM A) compensates for signal loss in the
receiver antenna cables, reduces system noise and improves uplink sensitivity.
The TMA can consist of a duplex filter. Duplex is the function that allows
com munication in two directions (sending an d receiving ) on one channel.
The TMA used for dTRU based products is dual duplex TM A (ddTMA).
Some configurations can use a TMA designed for receptio n only (rTMA).
