This is easy to fix, however, and there are a few main ways:

However, if you install your system to maximize your gain, you may end up overloading your amplifier. If you have excellent outdoor signal but lousy indoor reception, that’s generally considered a great situation for a signal booster. Handling too powerful a signal is another common reason. Generally speaking, the two antenna should have 6 to 7 meter of vertical separation to prevent this from happening. This should only happen to your amplifier if you place it too near an antenna, or if the indoor and outdoor antenna are installed too near one another. Think of a microphone and a speaker: when they are placed too close together, an unpleasant screeching noise emits from the speaker. Oscillation refers to electronic feedback. There are generally two reasons why an amplifier will turn off: oscillation, and handling too powerful a signal. Sometimes, your amplifier will shut itself off, and you may not understand why. If too much power is present, you may need to install an attenuator.Ĭell phone signal boosters are sophisticated pieces of equipment, and like any electronic device, can become overwhelmed. Too much, and the amplifier will automatically shut off. That’s what will determine how much signal the amplifier can take in and rebroadcast.

Most home boosters will range from +60 to +70 dB, while commercial boosters will have +70 dB and better downlink power.ĭecibels are measured exponentially. The more the gain, the more signal from the outdoor antenna is amplified. It simply measures how much the signal is amplified, using dB. To ensure the result, the outdoor signal should be as strong as possible.What makes one amplifier different from another? There are two main variables that make the determination: gain and downlink power. Please adjust the direction of the outdoor antenna until it catches good and steady signal. If still no signal reception after activating repeater, please check if outdoor antenna points to signal tower or elsewhere have strong signal and check if strength achieve -70dBm. Put the indoor antenna(s) in the middle of room, far away from the window and door.Ģ. The outdoor antenna should be on the housetop, at least 10 meters far away from the indoor antenna(s), better with stairs or wall(s) in between.

They should not be on the same horizontal line.

Triband 2G 3G 4G Signal Booster Technical Support:ġ.Please make sure the outdoor antenna is well isolated with the indoor antenna(s). 1.Fix up outdoor antenna reception on housetop and point to signal tower.Ģ.Connect outdoor antenna to "outdoor" port in repeater machine through cable.ģ.Connect indoor antenna(s) to "MOBILE" port in repeater through cable also.Ĥ.Plug power adaptor into AC power socket and finish installation.
