Our MR PowerMAX GSM900 booster kit is an optimal repeater for clients seeking a signal boost for voice calls in a moderate area, such as a home, small office, small warehouse, etc. It is for clients using any carrier that supports GSM900 on 900MHz.

It functions by receiving and boosting GSM900 at 900MHz frequency. This is on of the typical GSM frequencies for 2G (voice and text) in South Africa, Asia, and Europe. It is the best option for shoppers who travel or have imported cellphones as it operates on most African, Asian and European telephone carriers. The MR PowerMAX GSM900 Booster coverage range goes up to 1,000 square meters, allowing a widely spread cell signal that reaches your entire home or mobile home, restaurant/café, office, small warehouse, etc. and supports up to 75 coinciding users! This PowerMAX GSM900 booster was created to boost your GSM voice and text services for all supporting South African networks. Your MR PowerMAX GSM 900 booster system covers:

  • GSM Voice and Text – 900MHz
  • Vodacom Network
  • Up to 1,000sqm
  • Up to 75 Simultaneous Users


This PowerMAX GSM900 booster can focus in on boosting one precise frequency (in this case it boosts 900MHz) and can provide you with very good cellphone reception and reliability in places you would not have it. This booster functions best when it is positioned where you get the most signal around your building since it will be able to pick up even the slightest bit of cellular frequency, and send it through the GSM900 booster system using the coaxial cables.

We like to make it easy for you to install the signal booster system yourself with the easy-to-follow installation instructions that come with your purchases! The MR PowerMAX GSM900 kit comes with:  your externa aerial antenna, internal PowerMAX GSM900 booster, 10-meter coaxial cable, and AC/DC power source cables. When you set up the booster in the desired building the GSM 2G (voice and text) cell reception inside your building will be amplified up to 200-300%! Mobile Repeater South Africa wants to help out in any ways possible, so we offer you 100% free technical assistance throughout the entire process, so don’t hesitate to contact us at any time!

We like to keep our GSM900 booster kits simple and highly functional, which is why they are so easy to install yourself! The PowerMAX GSM900 booster, like all of our booster systems, is composed by 4 major parts:

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

Indoor PowerMAX GSM900 Booster: This is the device that obtains the signals from the coaxial cables, and amplifies the signal throughout the inside your building and makes it up to 3 times stronger than earlier.

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

The reasons you need a GSM signal booster 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, office, restaurant, etc. that block signal from entering clearly; living or working too far from your GSM carrier’s primary broadcast antenna; any mountains between you and the central antenna; or a thickly forested area in your area. Luckily, our engineering and design sections have premeditated these factors, and have developed a way to do away with all of them.
