Reduce Dropped & Missed Calls

Home booster kits reduce dropped & missed calls and extend battery life for multiple cellular devices.

1) Sleeping Mode: When no user calls, the device works in Sleeping mode, so as to achieve the purpose of energy saving.
2)Automatic Gain Control : When the downlink output signal is too strong or self-oscillated, booster can automatically reduce the gain and reduce the interference signal.
4)Automatic Power Shut-down : When the self-oscillation happens and the link attenuation value reaches 20dB, the MCU sends out the instruction and shut-down the PA.
5)MGC (Manual Gain Control): In order to install the booster conveniently, all frequency band of the booster have the Gain attenuation adjustment function, the adjustment scope is 0-20dB.
You can rotate the Manual Gain Control Knob to the OFF state and turn off the corresponding frequency band.
6) ALC(Automatic Level Control): Automatically adjust the output gain down to optimal figure while the output gain is above the optimal figure by the ALC circuit, this can greatly optimize the calling and data transfer quality.

Different points (with other amplifiers)


Coverage comparison (according to the strength of different signals):

Note: The amplifier kit in this link is the second set in the picture — amplifier with directional yagi and Whip angle antenna set

Outdoor Antenna

Directional Yagi antenna mount the outside antenna and point in the direction of the strongest signal. Includes pole and wall mounting hardware. Connects to booster with RG-58 coax cable (50 ft included with kit).

Home Booster
Indoor bi-directional amplifier boosts cell signal received from and sent back to the cell tower. Powered by a standard AC power supply.

Indoor Antenna
Whip antenna (omni-directional) rebroadcasts boosted cellular signal to multiple mobile devices. Antenna connects directly to booster.

Why You Want it?






Check your mobile phone frequency before purchase The booster can only amplify signal, it can’t create signal. If there is no outside signal, the booster will not work for you.

Please make sure you can make calls successfully outside your car. The booster can only work with cell phones that has the same frequency band as the booster.

Please check which band your cell phone is using firstly by the methods below:

For iPhone:

Dial *3001#12345#*, then press Call button Click ‘Serving Cell Info’ Check ‘Freq Band Indicator’;

For Android phone:

Download and install the app: LTE Discovery, tap ‘SIGNALS’ and check band number.

If it shows

Band 12/13/17

Band 5/4

Band 5/2

, please choose this booster. If the test result is other number, please choose another booster according to your band.
