Cellular Amplifiers/Repeaters (BDAs)

Repeater Systems

The Bi-Directional Amplifer/Repeater amplifies and repeats the outside cellular signal inside your building. The amplified signal is repeated via an indoor antenna. Likewise, the signal from your phone is repeated outside. Several models are available for iDEN (Nextel, Southern LINC, Mike) and 800MHz Cellular including in building and in vehicle models. Models for AT&T GSM, Sprint PCS and T-Mobile are expected later in 2004.

• High Output Power allows more Users on the System
• Safer Than Using Your Cellular Phone Without An Amplifier
• Extends the Life of Your Cellular Phone Battery
• FCC Type Accepted

A typical amplifier installation consists of the outdoor (donor) antenna connected by a length of 9913 Ultra Low Loss Cable to the amplifier. The amplifier is then connected to the interior antenna. To protect the amplifier from lightning strikes to the outdoor antenna, a coax lightning protector is recommended.

• Outside (Donor) Antenna: The Wilson Cellular 800MHz/Nextel directional antenna is recommended due to its high gain. The antenna must be aimed at the appropriate tower for maximum system performance.
• Cabling: Used to connect the outside antenna to the amplifier. Ultra Low Loss 9913 Coax Cable is recommended due to its low signal loss. RG-58 cable is not recommended due to signal loss. TV/Satellite coax is not compatible.
• Amplifier: Several amplifier/repeater options are available depending on your carrier, available signal strength (outside) and amount of amplification (coverage) needed.
• Interior Antenna: The Wilson Cellular Dual-Band Stealth antenna is frequently chosen as the interior antenna due to its easy mounting requirements. It is typically connected directly to the amplifier.

Options:

• Lightning Suppressor: Used to protect amplifier against lightning strikes to the outdoor antenna
• Splitters: Used to drive multiple interior antennas with a single amplifier. To drive multiple antennas you may need to move to a larger amplifier.
• Outdoor Coverage: Our systems can be used to provide improved outdoor coverage. Please contact our for more engineering team information.

Coverage: System coverage is dependant upon both the gain of the amplifier and the strength of the signal outside. Typically, if you are in an area with poor signal you are going to need the higher gain amplifiers. Areas of with good, strong signal can usually use the medium gain amplifiers. If you are unsure of which amplifier to select, contact our engineering team.
