  • MR PowerMAX GSM900/1800 | All GSM Networks

    Our MR PowerMAX GSM900/1800 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 and GSM1800 (900MHz and 1800MHz).

    It functions by receiving and boosting GSM900 at 900MHz and GSM1800 at 1800MHz frequency; which are the typical GSM frequencies for 2G (voice and text) in South Africa, Europe, and Asia. It is the best option for clients who travel or have imported cellphones as it operates on most African, Asian and European telephone carriers. The MR PowerMAX GSM900/1800 Booster coverage range goes up to 1,000 square meters, allowing a widely spread signal that reaches your entire home, office, mobile home, restaurant/café, small warehouse, etc. and supports up to 75 coinciding users! This PowerMAX repeater was created to boost your GSM voice for all supporting South African networks. Your MR PowerMAX GSM 900/1800 booster system covers:

    • GSM Voice – 900MHz and 1800MHz
    • Vodacom, Telkom, Cell C, and MTN Networks
    • Up to 1,000sqm
    • Up to 75 Simultaneous Users


    This PowerMAX GSM900/1800 booster can focus in on boosting two specific frequencies (in this case it is 900MHz and 1800MHz) and can provide you with very good cellphone signal in places you would not have it. This booster works best when it is positioned where you get the most signal around your building, and is pointed towards the signal, since it will be able to pick up even the slightest bit of signal frequency and send it through the GSM booster system using the coaxial cables.

    We like to make it easy for you to install the signal booster kit yourself with the easy-to-follow installation instructions that come with your purchases! The MR PowerMAX GSM900/1800 kit comes with:  your externa aerial antenna, internal PowerMAX GSM900/1800 booster, 10-meter coaxial cable, and AC/DC power source cables. When you set up the repeater in the desired building, the GSM 2G (voice) cell reception inside your building will be significantly 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. It’s our duty to assist you!

    We are aware that there is quite a bit of competition in our area of the market, but since we have been developing our PowerMAX GSM booster kits for over 10 years, we have the experience needed to provide you with the best mobile signal coverage.

    We believe in the superiority of our products, and their ability to boost the 2G GSM reception that is around your building; so much so that we offer our clients a 15-day money back guarantee; and love to give you the perk of free shipping. Furthermore, all government and corporate institutions have the opportunity to pay after 30 days with their PowerMAX GSM booster kit!

    We like to keep our booster kits simple and highly functional, which is why they are so easy to install yourself! The PowerMAX GSM 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 GSM signal you have outside your home or office building, and sends it through the PowerMAX GSM 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 GSM booster at high speeds.

    Indoor PowerMAX GSM900/1800 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 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; working or living too far from your GSM carrier’s primary broadcast antenna; any mountain(s) between you and the central antenna; or a thickly forested area near you. Luckily, our engineering and designing sections have premeditated these factors, and have developed a way to do away with all of them.
