The UNHLQ-900/1800/2000 RF Combiner is high performance 3-input RF combiner that can simultaneously transmit signals of GSM900, DCS1800 and WCDMA system to a single set of indoor signal distribution system. The RF combiner features low insertion loss, high isolation and excellent temperature stability.
Usage Instruction
- Fix the Combiner and prepare the RF jumpers.
- Switch off the devices of signal source and then connect the combiner with the devices via the jumpers. The connectors on the Combiner must be connected to the corresponding devices; otherwise, the devices will be burnt due to wrong VSWR.
