TMA TWIN 1800/2100/2600
Designed to be deployed in co-located 1800, 2100 and 2600 MHz systems with wideband antennas, this Tower Mounted Amplifier provides gain in all the bands.
FEATURES
- Improved base station sensitivity through gain in the 1800, 2100 and 2600 uplink
- Excellent noise figure performance
- Full AISG operation and RET antenna support, AISG2.0 compatible
- Small and light for minimum visual impact
