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), 800MHz Cellular, and 1900 MHz PCS including in building and in vehicle models.

If you would like our engineers to help design an amplifier system for your building, please complete our Amplifier Questionnaire (PDF).

Features:

• Advanced Electronics Receive & Transmit Better Than Your Cellular Phone
• Significantly Increases Your Cellular Phone's Range on Send & Receive
• 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 LMR-400 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: Choose from a variety of single band 800 MHz, single band 1900 MHz,  or dual-band high gain directional yagi or omni-directional 360 degree antennas. 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 LMR-400 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: Choose from a variety of wall mount and ceiling mount In Building Wireless Antennas for use with wireless repeater systems.

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.
