GSM 850Mhz Cell Phone Signal Boosters / Marine Signal Booster High Power


Cell Phone Signal Booster Descrption:

GREETWIN cellular signal booster boosting your cellular signal anywhere.

Signal booster kits are offered with various connector types. All kits come with cables and antennas which match the booster connector type. If you need to purchase extra extension cables or antennas please be sure to match the booster connector type.


The Marine Signal Booster Kit is the best kit for boosting cell signal in your boat or marine craft.
Eliminate dropped calls and increase data speeds with a signal booster.
Indoor Cell Phone Signal Booster series is an ideal solution for wireless system in small/medium businesses and home users looking to enhance indoor wireless connectivity. It is connected via coaxial cable to Donor Antenna and Service Antenna, Donor Antenna is placed outside the building where it has easy access to BTS signal, and the Service Antenna is placed in the building where it can extend radio coverage to the blind area. And Automatic Gain Control (AGC) to avoid the Booster from over saturation, therefore maintaining a high voice quality and avoid adding interference to network. With good looking & super compact design also make it attractive. Besides, it is easy installation feature is also for individual customers to install the booster by themselves, and it does not need much professional knowledge and instrument. 
The repeater improves mobile signals with no negative impact on human health.

Cell Phone Signal Booster Installation:


Installing the Marine Signal Booster Kit is very easy.

To start, mounting the Marine Omnidirectional antenna, as high up as possible on the boat or marine . Run the attached cable into the boat and connect the cable to the signal amplifier's Outside Antenna port. To the Inside Antenna port, connect the inside antenna cable and run to the inside panel antenna, which you'll mount either on the ceiling or the wall in the location where you'll be using your mobile devices . Turn on the repeater and you should immediately start receiving boosted signal.
