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

This MR PowerMAX 900/3G XT+ Booster works on GSM900 at 900MHz and 3G at 2100MHz frequency. These are the typical frequencies for 2G (voice and text) and 3G (data) in UK and most of Europe. This one of the best options for corporate clients, as it operates on most European telephone carriers and supports a vast number of users. The MR PowerMAX 900/3G XT+ coverage goes up to 5,000 square meters, 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 UK networks. Your MR PowerMAX XT+ Repeater booster kit covers:

  • GSM Voice and Text – 900MHz
  • 3G Data – 2100MHz
  • All Supporting UK Carriers
  • Covers up to 5,000 square meters
  • 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 repeater. This booster works best when it is positioned where you get the most signal around your establishment and is pointed towards the direction said the signal is strongest; because it will be able to pick up even the slightest bit of frequency and send it through the PowerMAX XT+ system by means of the coaxial cables.

We like 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 PowerMX 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, and of course, your 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%! 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 or send us an e-mail at any time!

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

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

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

Indoor dual band MR PowerMAX 900/3G XT+ Repeater: This is the device that obtains the signals from the exterior Aerial antenna by means 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, except with your GSM and 3G signal.
