CM800/70 - Cellphone Mate SureCall 70dB In-Building Wireless 800MHz Cellular Bi-Directional Amplifier (Repeater)

High gain 70dB 800MHz Cellular Repeater provides nearly double the coverage of a 65dB repeater. Built in uplink and downlink attenuators allow you to adjust gain to your specifications.

SureCall CM800/70 repeaters extend cellular services in poor coverage areas by amplifying both transmit and receive signals. The amplifiers reduce problems with signal fades and dropped calls while improving voice quality, service range and access. These multi-mode amplifiers are designed to offer a cost-effective solution for use in buildings. Cellphone-Mate SureCall amplifiers are network compatible and enhance the cellular phone user's satisfaction without compromising the operation of the cellular system.

This Amplifier-Repeater greatly improves signal strength inside a building when using your cellular phone. It does this without a physical connection to your phone, allowing you to walk freely during a call. It even allows multiple phones to be used simultaneously.

The signal from the cellular tower is received by the outside antenna and then amplified and repeated to your phone through the inside antenna. When the phone transmits, it is received by the inside antenna and then amplified/repeated through the outside antenna to the cellular tower.

The higher gain of the CM800/70 repeater allows it to provide greater coverage area and more easily drive multiple interior antennas. Repeater includes AC power supply and mounting bracket.

Features:

• 70dB gain manually adjustable in 1dB increments down to 33dB
• Automatic gain control (AGC) to help prevent overload
• Uplink/Downlink oscillation detection (individual LEDs)
• CDMA rho: > 0.95
• Wireless operation - no physical connection to cellular phone
• 3 Watts Output Power when used with recommended 9dB or higher gain exterior antenna
• Increases signal strength in buildings for 800MHz Cellular frequencies
  • 824-894MHz
  • Analog/Digital (CDMA, TDMA, GSM)
  • 1900MHz band is unaffected/unamplified
• Allows multiple phones to be used simultaneously
• Provides almost double the coverage area of a 65dB amplifier

When designing your system, please be sure to allow for 70' of separation between the interior and exterior antennas (20' which must be vertical).

Requires:

• Outside antenna (recommend Yagi)
• Inside antenna (recommend Ceiling Mount Dome Antenna)
• Ultra Low Loss Cable

Optional:

• Splitters
• Lightning Protector
• Test Cable/Adapter to aim Yagi (highly recommended!)

Compatibility:

• Compatible with all 800MHz Cellular providers (CDMA, TDMA, GSM, Analog). For example, most Verizon, AT&T, Alltel, US Cellular and many more
• Not compatible with 1900MHz PCS (Sprint PCS, T-Mobile, Qwest)
• Not compatible with iDEN (Nextel, Southern LINC, Mike)
• Not compatible with 1700MHz AWS (T-Mobile US 3G)

  Please note that many carriers (Verizon, AT&T, Alltel, US Cellular and others) operate on 800MHz Cellular, 1900MHz PCS or both depending upon your location. CheckZip can be used to determine which frequencies are licensed by your carrier in your area.
