The Tetra UHF VHF Signal Booster, It has a simple structure to transparently convey and amplify the wireless signal (at the same frequency) between the BTS (Base Transceiver Station) and mobiles in a Dual wireless network, it picks up the signal from the BTS via the Donor Antenna, linearly amplifies the signal, and then retransmits it via the Coverage Antenna (or the Indoor Signal Distribution System) to the weak/blind coverage area. And the mobile signal is also amplified and retransmitted to the BTS via the opposite direction.
When the repeat antenna receives uplink signals from a subscriber, the signals will undergo the processing of a low-noise amplifier, filter, and power amplifier first, and then be transmitted to the base station, thus accomplishing the connection between subscribers in the signal blind area and base station.
In this way, the blind areas are eliminated.
Considering receiving signal intensity and coverage size may vary with sites where the repeater is located, it is necessary to control the gain and output of the repeater.
Additionally, considering the fading effect in spatial signal transmission, auto amplitude fixing for output is required.
For this purpose, MGC and ALC circuits are included in the uplink/downlink channels.
- Aluminum-alloy casing with IP65 protection has a high resistance to dust, water, and corroding
- Low interference to BTS by adopting a linear amplifier with high gain and low noise
- Adopting filter with high selectivity and low insertion loss eliminates interference between uplink and downlink
- The USB port provides a link to a notebook for local supervision or to the built-in wireless modem to communicate with the NMS (Network Management System) that can remotely supervise the repeater's working status and download operational parameters to the repeater.

I.Site Survey before Installation
Before you install, the installer should contact the person responsible for the project, understand whether there are installed conditions in the installation site.
Specifically include Installation site, surroundings (Temperature and Humidity), power supply, and so on.
If qualified should go live on-site survey with related personnel. The repeater is designed that can working outdoors, operating temperature is -25ºC~65ºC, humidity is ≤95%, which can be adapted to most areas of the natural environment.
II.Recommended Environmental Requirements:
1.Installation area non-corrosive gases and fumes, Electromagnetic interference field strength ≤140dBμV/m(0.01MHz~110000MHz).
2.Mounting height should facilitate RF cable routing, cooling, safety, and maintenance.
3.Should provide a set of independent and stable 150VAC~290VAC(Nominal 220V/50Hz)AC Power. It must not be shared with other high-power appliances telecommunications equipment.
4.Lightning protection devices must be installed in the building, and it should have sufficient strength and stability.
