Product Description
The Maniron 2100MHz 2T2R Tower Mounted Amplifier (TMA) is a high-performance solution designed to boost mobile signal strength and increase in-building coverage. By improving uplink sensitivity and compensating for feeder loss, it significantly enhances the overall network quality for BTS systems. It features a rugged aluminum housing, supports AISG 2.0, and is rated IP67 for both indoor and outdoor environments.
Application Scenarios
- Uplink Sensitivity Enhancement: Improves signal reception from mobile devices to the base station.
- In-Building Coverage: Increases signal penetration and strength in commercial and industrial buildings.
- Feeder Loss Compensation: Offsets signal attenuation caused by long RF cable runs.
- Network Capacity Optimization: Improves call success rates and data throughput in 2100MHz bands.

Frequently Asked Questions
- Q1: Does this TMA support AISG monitoring?
- A: Yes, it supports AISG mode for remote alarm management and power supply control, compliant with ETS 300 342-3 EMC standards.
- Q2: What is the benefit of the By-pass mode?
- A: In case of a DC power failure, the TMA automatically switches to By-pass mode with a return loss of 15dB min, ensuring basic signal continuity.
- Q3: Can it be installed outdoors?
- A: Yes, the unit is IP67 rated and constructed with an aluminum housing, making it suitable for both indoor and harsh outdoor environments.
- Q4: What are the connector options?
- A: The standard configuration comes with 4 high-quality 4.3-10-female connectors for low PIM performance.
