CM2020-68 | 3G Enterprise In Building Cellphone Amplifier

68dB Cellular / 68dB PCS | boost signal for buildings up to 20,000 sq. ft.

  • Linear design
  • Reconfigurable, dual band, fits any size
  • 68dB Avg. Gain,73 Max. Gain
  • Manually adjustable at 1 dB increments
  • Features Automatic Shutdown to prevent overload
  • Supports multiple users
  • Uplink/Downlink Oscillation detection (individual LEDs)

The CM2020 68dB amplifier is the most powerful linear dual-band amplifier on the market today and extends cellular services in poor coverage zones where the signal is weak due to topography, building materials or structural design. This full-featured amplifier includes adjustable gain control and automatic shutdown for maximum flexibility. Ideal for low signal and/or large coverage areas. Covers up to 20,000 square feet. Supports multiple simultaneous callers using different carriers.

Note: Our boosters and amplifiers cannot transmit cell signals without an outside and inside antenna connected by a cable.

We strongly recommend these antennas and cables as accessories for our boosters and amplifiers.

However, the number of antennas, length of cable, or connectors needed can vary according to the size and make of the structure, lack of signal strength, or where the structure resides. Or you can contact us or our reseller to find out what you need.

The signal is received by the outside antenna from the cell tower, then AMPLIFIED and transmitted to your phone through the inside antenna. When the phone transmits, the signal is received by the inside antenna, then AMPLIFIED and transmitted to the cell tower through the outside antenna.

 

Steps

1. Mount outside antenna (mounting kit with stucco screws provided)

 

2. Using CM400 cable, connect the dome antenna to the side of amplifier marked OUTSIDE

 

3. Mount dome antenna on the ceiling,

 

4. Using CM400 cable, connect the dome antenna to the side of amplifier marked INSIDE

 

5. Connect the Power Cord (make sure the booster’s power switch is in the OFF position).

 

6. Turn on the booster’s power switch. The LED light will glow, indicating that the booster is ready to use.

 

7. Adjust dipswitches per the user manual’s instructions for ideal reception
