OneBase™ Diplexed Dual Band Tower Mounted Amplifier
850/1900 MHz TMA for Diplexed Feeder

Designed for the highest reliability even in the most demanding installation environments.

The tower mounted amplifiers from Andrew Solutions help optimize network performance and represent the ideal solution for coverage and capacity enhancement.

By improving uplink performance, Andrew Solutions tower mounted amplifiers (TMAs) ensure optimum coverage of fringe areas, weak spots, and indoor locations. Easily installed in any wireless system, TMAs provide multiple benefits:

Improved sensitivity—reducing dropped calls and failed connection attempts. Enhanced signal quality—improving voice clarity and data speed. Lower handset output—extending talk time, reducing interference in GSM/EDGE, UMTS, and CDMA systems.

The dual band, dual duplex TMA is part of the OneBase™ product family, which combines the Andrew Solutions products and technology into complete solutions for use in integrated base station systems. The self-contained body is engineered to ensure the highest reliability in severe environments while featuring a compact size and attractive appearance.
