Our MR PowerMAX Tri-Band booster kit is an optimal repeater for clients seeking a signal boost for voice calls, 3G and 4G/LTE signal coverage in a moderate sized building. It is for clients using any carrier that supports GSM 900/1800 and 3G. This Tri-Band booster is one of the most versatile systems on the market, since it is able to boost 3 different frequencies at the same time, and therefore provides you with good coverage for all 3 different services. Another perk is its compatibility with all GSM/3G supporting South African cellphone networks.

This PowerMAX Tri-Band booster is so versatile because it works on 900HMz, 1800MHz and 2100MHz frequencies. The MR PowerMAX Tri-Band booster coverage goes up to 1,000 square meters, allowing a widely spread signal that reaches your entire home, R.V., office, restaurant, etc. and supports up to 75 coinciding users! This PowerMAX Tri-Band booster was created to boost your GSM900/1800MHz and 3G data for all supporting South African networks. Your MR PowerMAX Tri-Band booster kit covers:

  • GSM 900, GSM 1800, and 3G
  • Voice and Text, 3G and 4G LTE
  • Up to 1,000sqm
  • Up to 75 Simultaneous Users


This PowerMAX Tri-Band booster can focus in on boosting three specific frequencies (900MHz, 1800MHz, and 2100MHz) and provides you with very good signal in places you would not otherwise have it. This booster works best when it is positioned where you get the most cellphone signal around your building, since it will be able to pick up even the slightest bit of frequency and send it through the Tri-Band booster system from the external antenna to the internal re-broadcast system using the coaxial cables.

Our teams at Mobile Repeater South Africa like to make it easy for you to install the booster yourself with the easy-to-follow installation instructions that come with your purchase! The MR PowerMAX Tri-Band booster kit comes with:  your externa aerial antenna, internal PowerMAX Tri-Band booster box, internal rubber whip re-broadcast aerial antenna, 10-meter coaxial cable, and AC/DC power source cables. When you set up the Tri-Band booster in the desired building, the 2G, 3G, and 4G reception inside your building will be significantly amplified, sometimes up to 400%! Additionally, 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 are aware that there is quite a bit of competition in our neighborhood of the market, but since we have been developing our PowerMAX Tri-Band boosters for over 10 years now, we have the experience needed to provide you with the best cell signal coverage.

We believe in the superiority of our booster systems and accessories, and their ability to boost the 2G, 3G and 4G LTE reception that is around your building; so much so that we offer you a 15-day money back guarantee with every single purchase; and love to give you the perk of free shipping. Furthermore, all government and corporate establishments have the opportunity to pay for their booster after 30 days with their PowerMAX Tri-Band booster kit!

Mobile Repeater South Africa enjoys keeping our booster kits simple and highly functional. So simple, indeed, that you can install them all by yourself! The PowerMAX Tri-Band booster, like all of our boosters, 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 cellphone signal you have outside your home or office building, and sends it through the PowerMAX Tri-Band 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 Tri-Band booster at high speeds.

Indoor PowerMAX Tri-Band Booster: This is the device that obtains the signals from the external antenna through coaxial cables, and amplifies the signal throughout the inside your building and makes it up to 4 times stronger.

Internal Rubber High-Gain Tri-Band Panel Antenna: This is the product that, once the internal PowerMAX Tri-Band Repeater receives the amplified signal, is in charge of re-broadcasting the signal through your building.
