  • GSM 900, 1800 or 3G
  • 5000 + sq m coverage


The MR UltraMAX 37dB Repeater is specifically designed for large area applications such as hotels, hospitals and commercial office buildings. The UltraMAX repeater is designed to improve the call or data transmission quality of an area by receiving, amplifying and re-transmitting signals of the base station mast into a specified area. The effective coverage area will depend on the strength of the signal being received by the outdoor antenna. The UltraMAX repeater has 90dB gain and is available in GSM 900MHz, DCS 1800MHz and 3G 2100MHz frequency bands.


This unit is used in conjunction with a indoor network of antennas and please contact our sales team for free advice and design from plans to help you gauge whats needed and costs involved. Free advice can be received from

Most in-building commercial repeater applications require multiple indoor coverage aerials fed from the main repeater unit to provide the best signal distribution across the building. The UltraMAX repeater unit can accommodate up to 50 indoor coverage aerials and hundreds of meters of cabling. For indoor coverage on multiple networks it is possible to connect more than one UltraMAX base unit of different frequencies with a low-loss frequency combiner to provide dual-band or tri-band signal coverage to your indoor antenna system.
