Our PowerMAX 900/3G XT+ Booster kit is an optimal repeater for clients seeking a signal boost for voice calls, text, and 3G data in a large area, such as an office building/floor, large home, restaurant or cafe, conference room, moderate theater, etc. It is for clients using any carrier that supports GSM900 and 3G (900MHz and 2100MHz) Voice, Text, and Data.

This MR PowerMAX 900/3G XT+ Booster works on GSM900 at 900MHz and 3G at 2100MHz frequencies. These are the typical frequencies for 2G (voice and text) and 3G (data) in South Africa. This one of the best options for corporate clients, as it operates on most South African telephone carriers and supports a vast number of users. The MR PowerMAX 900/3G XT+ coverage goes up to 2,500 square metres, allowing a widely spread, high power signal that reaches your entire office, home, conference room, etc. and supports up to 100 users at the same time! This MR PowerMAX 900/3G XT+ was designed especially to boost your GSM voice and 3G data for all supporting South African networks.

Your MR PowerMAX XT+ Repeater booster kit covers:

  • GSM Voice and Text – 900MHz
  • 3G Data – 2100MHz
  • All Supporting South African Carriers
  • Covers up to 2,500 square metres
  • Up to 100 Simultaneous Users

This PowerMAX 900/3G XT+ can focus in on boosting and improving two specific frequencies (in this case it is 900MHz and 2100MHz), and provides you with very good signal in places you would not have it without the installation of our booster. This booster works best when it is positioned where you get the strongest signal around your establishment, and is pointed towards the direction said signal is best; because it will be able to pick up even the slightest bit of frequency and send it through the PowerMAX XT+ booster system through the use of the coaxial cables.

Mobile Repeater’s team likes to make it easy for you to install the repeater yourself with the easy-to-follow installation instruction manual, and all the necessities that come with your every purchase!

The PowerMAX 900/3G XT+ kit comes with:

  • PowerMAX XT+ GSM 900/12100MHz repeater
  • External Aerial Antenna
  • Indoor Rubber Whip Rebroadcast Aerial Antenna
  • 10-meter Coaxial Cable
  • AC/DC Power Source Cables
  • Installation Manual

When you set up the repeater in the desired building, the 2G (GSM voice) and 3G (Data) reception inside your building will be significantly boosted, sometimes up to 200% in mere seconds! Also note: Mobile Repeater wants to help out in any ways possible, so we offer you 100% free technical assistance throughout and after the whole installation process, so please don’t hesitate to call us of send us and e-mail at any time!

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 900/3G XT+ boosters over many years, we have the expert development and skills needed to provide you with a professional mobile signal coverage and customer care experience.
We believe in the superiority of our products, and their ability to boost the GSM and 3G reception that is around your building; so much so that we offer all of our clients alike a 15-day money back guarantee with every purchase, and love to give you the bonus of free shipping. Also, all government and corporate establishments have the chance to pay after 30 days with their MR PowerMAX 900/3G XT+ Booster!

We enjoy keeping our booster kit simple and highly functional, which is why it is so easy to install by yourself! The MR PowerMAX 900/3G XT+ Booster, like all of our boosters, is composed by 4 major parts:

External Aerial Antenna: The exterior aerial antenna is essential to the booster’s functionality because it is the external high power antenna that receives any GSM and Data signal (900 and 2100MHz) you have outside your building, and sends it through the MR PowerMAX XT+ Booster system.

Coaxial Cable: The coaxial cable is a 10 meter long cable that are intended to transfer the cell signal from the external aerial antenna to the indoor MR PowerMAX XT+ booster system at high speeds. You can find extra cables (and other essentials) in our Accessory Tab if you might need them.

Indoor dual band MR PowerMAX 900/3G XT+ Booster: This is the device that obtains the signals from the exterior aerial antenna by use of the coaxial cables, and amplifies the signals throughout the inside your building and makes it up to 2 times stronger than earlier.

Indoor Rubber Whip Rebroadcast Antenna: This is the part which acts like a second antenna indoors, but instead of receiving exterior signal, it obtains signal from the indoor PowerMAX repeater box, through the coaxial cables, and rebroadcasts it inside your facility, as a wifi modem would in the case of internet frequencies.
