Product Description

MR PowerMAX GSM900 / 3G Booster | Calls and 3G

Our MR PowerMAX GSM900 / 3G booster kit is an optimal repeater for clients seeking a signal boost for calls, text, and 3G. It is for clients using carriers that support GSM900 services (900MHz frequency) and 3G services (2100MHz). This repeater boosts your GSM900 and 3G services for all South African networks.

The booster operates by working on GSM900 at 900MHZ frequency, which is the typical frequency for 2G (voice and text) in the South Africa and Asia. The MR PowerMAX GSM900 / 3G Repeater coverage goes up to 1,000 square meters, allowing a widely spread, strong signal that reaches your entire home, office, moving home, cabin, , etc. and supports up to 75 simultaneous users! This PowerMAX GSM 900 / 3G repeater was created to boost your voice and 3G services for SA networks. Your MR PowerMAX GSM 900 / 3G booster kit covers:

  • Voice – 900MHz supporting carriers
  • 3G – All South African Networks
  • Up to 1,000sqm
  • Up to 75 Simultaneous Users


This PowerMAX GSM900 / 3G repeater can focus in on boosting two specific frequencies (in this case it is 900MHz and 2100MHz) and provides you with very good signal in places you would not otherwise have it. This repeater works best when it is positioned in the place where you get the most signal around your building, and is pointed in the direction the signal comes from, since it will be able to pick up even the slightest bit of frequency and send it through the booster system via the coaxial cables.

We like to make it easy for you to install the booster kit yourself with the easy-to-follow installation instructions manual that come with all purchases! The MR PowerMAX GSM900 / 3G kit comes with:  your externa aerial antenna, 10 meters of coaxial cables, internal PowerMAX booster box, and AC/DC power source cables. When you set up the repeater in the desired building, once you connect the AC/DC power cables, the 2G and 3G reception inside your building will be significantly amplified, sometimes up to 300%! Mobile Repeater also wants to help out in any ways possible, so we offer you 100% free technical assistance throughout the entire process, so call us or e-mail us any time. Please let us know what we can do to help you at any point along the installation procedure. It’s our duty to assist you always!

We boost your cell signal in an exclusive way. This is how:

External Aerial Antenna: The exterior aerial antenna is essential to the booster’s functionality because it’s the external antenna that receives any 2G and 3G signal you have outside your home or office building, and sends it through the PowerMAX GSM900 / 3G system.

Coaxial Cables: The coaxial cables are 10 meter long cables that are intended to transfer the cell signal from the external aerial antenna to the indoor GSM900 / 3G booster at the highest speeds possible.

Indoor PowerMAX GSM900/ 3G Repeater: This is the device that obtains the cellular frequencies from the coaxial cables, and amplifies the signal throughout the inside your building; making it 2-3 times stronger than earlier. This is the device that is connected to the AC/DC power supply cables.

AC/DC Power Supply: The repeater’s power supply.

The reasons you need a mobile repeater is probably due to things that are a little out of your reach, such as the building materials used in the construction of your home, high-rise, RV, etc. that block signal from entering; working or living too far from your carrier’s primary broadcast antenna; the mountain(s) or dip(s) in your area; or the densely forested area in your city or town. These are all contributing influences to the poor (or nonexistent) cell signal you’ve had to deal with. Luckily, our designer and engineer teams have premeditated these factors, and have developed a solution to do away with all of them.
