Our PowerMAX 900/1800 XT+ Booster kit is an optimal repeater for clients seeking a signal boost for voice calls in a very large area, such as an office building floor, large home, restaurant or diner, conference room, etc. It is for clients using any carrier that supports GSM900 and GSM1800 (900MHz and 1800MHz) Voice.

This PowerMAX 900/1800 XT+ Booster works on GSM900 at 900MHz and GSM1800 at 1800MHz frequency. These are the typical GSM frequencies for 2G (voice and text) in UK and most of Europe. It is one of the best options for corporate clients, as it operates on most European telephone carriers and supports a vast number of users. The PowerMAX 900/1800 XT+ coverage goes up to 5000 square meters, allowing a widely spread, high power signal that reaches your entire office, home, conference room, etc. and supports up to 200 users at the same time! This PowerMAX 900/1800 XT+ was created to boost your GSM voice for all supporting UK networks (except 3G). Your PowerMAX XT+ Repeater booster kit covers:

  • GSM Voice and Text – 900MHz and 1800MHz
  • All Supporting UK Carriers
  • Covers up to 5000 square meters
  • Up to 200 Simultaneous Users

This PowerMAX 900/1800 XT+ can focus in on boosting two specific frequencies (in this case it is 900MHz and 1800MHz) and provides you with very good signal in places you would not have it without the installation of this repeater. Our booster works best when it is positioned where you get the most signal around your building, and is pointed in the direction said signal is strongest; since it will be able to pick up even the slightest bit of frequency and send it through the PowerMAX XT+ system through the coaxial cables.

We like to make it easy for you to install the repeater yourself with the easy-to-follow installation instruction manual that comes with your every purchase! The PowerMX 900/1800 XT+ kit comes with:  PowerMAX XT+ GSM 900/1800MHz repeater, External Aerial Antenna, Indoor Rubber Whip Rebroadcast Aerial Antenna, 10-meter Coaxial Cable, AC/DC Power Source Cables, and Installation Manual. When you set up the repeater in the desired building, the 2G (GSM voice) 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 contact us at any time!

We enjoy keeping our booster kit simple and highly functional, which is why it is so easy to install yourself! The PowerMAX 900/1800 XT+ Repeater, like all of our repeater, 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 high power antenna that receives any GSM signal you have outside your building, and sends it through the PowerMAX XT+ 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 PowerMAX XT+ system at high speeds. You can find extra cables in our Accessory Tab.

Indoor PowerMAX 900/1800 XT+ Repeater: This is the device that obtains the signals from the exterior Aerial antenna through coaxial cables, and amplifies the signal 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 repeater box, through the coaxial cables, and rebroadcasts it inside your facility, as a wifi modem would, except with your GSM signal.
