Tower-Mounted Amplifiers (TMAs) minimize the cost of network expansion and improve the
quality of service, allowing carriers to increase profitability from new and existing services.
quality of service, allowing carriers to increase profitability from new and existing services.
ClearGain TMAs improve signal quality by boosting the uplink (RX) signal of a mobile system
immediately after the antenna. This compensates for the loss in signal strength that occurs
when the signal is passed through the coaxial feeder cable to the base transceiver station (BTS)
at the base of the tower. These TMAs perform this amplification with the lowest possible noise
contribution, resulting in a substantial increase in receiver performance and an improvement in
overall coverage. These improvements in quality of service allow mobile subscribers to place more
calls, make longer calls, and successfully complete calls in an expanded geographic area, resulting
in increased revenue.

Benefits:
• Small size and low weight. Allows for easy installation with minimal visual impact and
in weight-restricted implementations.
• Improved uplink coverage. TMAs enable base stations to receive mobile signals more clearly
in a wider coverage area than could otherwise be achieved.
• Increased RF performance. By improving signal quality and/or reducing mobile phone power
transmission, TMAs provide more successful call attempts, a reduction in dropped calls,
maximized data rate, improved call quality and the extension of handset battery life.
