visits and lower maintenance
• MTS 4 fully complies with the new ROHS
directive
Compact Design Optimises
Site Space
Smaller, lighter and even more versatile than its
predecessor, the MTS 4 is a high performance
base station with improved power efficiency and
lower operating costs.
• A worthy successor to the popular EBTS with a
more compact design and upgraded features for
enhanced performance
• 50% lighter - now only 148 kg for easier
installation
• 40 cm lower allowing more flexible fitting
options
• 33% less power consumption
• ‘Best in Class’ receiver sensitivity
• Wide frequency range of 350 – 470 MHz
• Top cable entry and bottom to top cooling
airflow allows the cabinet to be placed up
against a wall or neighbouring equipment,
saving additional space
• Sites that do not allow for any receiver diversity
can be set up with one single omni antenna
pole, avoiding expensive mast constructions and
complying with environmental requirements
