3 Way frequency combiner can connect multiple repeater units to form either a dual-band or Tri-Band system using large application repeater units. This accessory allows you to install separate outdoor aerial for each frequency band (the most common in the UK and worldwide are GSM 900MHz, DCS 1800MHz, 3G UMTS 2100MHz, and LTE 800/2600MHz) and separate booster units so that you get the maximum signal coverage per frequency band. The combiner is used at the repeater output ports to combine all the signals into 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 the aerial direction and signal strength for each frequency independently. The frequency combiner unit will enable you to connect our industrial repeater units’ output signals 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 premises.
