Frequency Combiner
The Tri-Band Frequency Combiner can be used to connect multiple mobile booster units together to form either a dual band or Tri-Band system using large application mobile booster units.
This accessory allows you to install separate outdoor aerial for each frequency band i.e. GSM 900MHz, DCS 1800MHz and 3G UMTS 2100MHz and separate mobile booster units so that you get the maximum signal coverage per frequency band. The combiner is used at the mobile booster output ports to combine all the signals on to one indoor aerial network.
For large applications it is better to use separate single band repeater units rather than a single dual-band or tri-band unit because this allows for higher power levels per band and the flexibility to control aerial direction and signal strength for each frequency independently.
The frequency combiner unit will allow you to connect the output signals of any of our industrial repeater units together to for a dual band 900/1800MHz, or a Tri-Band 900/1800/2100MHz coverage network inside the building without having multiple aerials for each frequency band inside the premesis.
