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.

 Ultra-Low-Loss Coaxial Cable  



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.
Note: Make sure Inside and outside antenna are 60’ apart

 
Optimizing Reception Using Dials:

Step 1: When you receive the booster, the PCS (1900 MHz frequency) dial on the top and the Cellular
(800MHz frequency) dial in the middle and the AWS LTE (2100 MHz frequency) should be each set at 65dB. If the ALERT light turns on for either band’s dial, it means that the booster is oscillating on that band.

If this happens, turn down the respective dial by 5dB, or for example, from 50 to 45. The ALERT lights
will flash for 20 seconds, the booster will automatically shut down, then restart.

 
Step 2: If the ALERT lights for either band continue to blink, turn the respective blinking knob down by
another 5dB or until the light stops flashing.

 
NOTE: During this process of adjusting dBs for either band, continually monitor the bars on your cell
phone to gauge reception.
