Our PowerMAX GSM 900 XT+ Booster kit is an optimal repeater for clients seeking a signal boost for voice calls in a very large area, such as a large home, an office building, a restaurant or dinner, conference room, moderate theater, etc. It is for clients using any carrier that supports GSM900 (900MHz) Voice.

This PowerMAX GSM 900 XT+ Booster works on GSM900 at the 900MHz frequency. This is the typical frequency for 2G (voice and text) in the 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 huge number of users. The PowerMAX GSM 900 XT+ coverage goes up to 5,000 square meters, allowing a widely spread, high power signal that reaches your complete office, home, conference room, etc. and supports up to 200 users at the same time! This PowerMAX GSM 900 XT+ was designed especially to boost your GSM voice for all supporting UK networks. Your PowerMAX GSM 900 XT+ Repeater booster kit covers:

  • GSM Voice and Text – 900MHz
  • All Supporting UK Carriers
  • Covers up to 5,000 square meters
  • Up to 200 Simultaneous Users


This PowerMAX GSM 900 XT+ can focus in on boosting and improving two specific frequencies (in this case it is 900MHz), and provides you with very good signal in places you would not have it without the installation of this 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 GSM XT+ system by means of the coaxial cables.

We like to make it easy for you to install the repeater with the easy-to-follow installation instruction manual, and all the necessities that come with your every purchase! The PowerMAX GSM 900 XT+ kit comes with:  Internal PowerMAX GSM 900 XT+ repeater, External Aerial Antenna, Indoor Rubber Whip Rebroadcast Aerial Antenna, 10-meter Coaxial Cable, AC/DC Power Source Cables, and your Installation Manual.

When you set up the repeater in the desired building, the 2G (GSM voice) signal and reception inside your building will be significantly boosted, sometimes up to 200%! Mobile Repeater UK 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  PowerMAX GSM 900 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 900 signal you have outside your building, and sends it through the MR PowerMAX GSM 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 GSM XT+ system at high speeds. You can find extra cables (and other necessities) in our Accessory Tab.

Indoor PowerMAX GSM 900 XT+ Repeater: This is the device that obtains the signals from the exterior Aerial Antenna by means of the coaxial cables, and increases 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 GSM XT+ repeater box, through the coaxial cables, and rebroadcasts it inside your facility, as a wifi modem would, except with your GSM frequencies.
