  • Page 12 For example, an SG900-6 antenna with a CC20/900 cable has a net gain of 2dB (i.e. +8 dB – 6 dB) at 900 MHz. The 105U-L-R module has no limitation on antenna gain, as this module does not incorporate a radio transmitter.

  • Page 13: Radio Transmission Distances

    1. ELPRO recommends using the 105-G module as a repeater unit between 105U- L-T and 105U-L-R modules. 2. To use a repeater unit, the 105U-L modules and the repeater module must be configured using the supplied configuration software. The factory default configuration described in the Quick Start Guide cannot use a repeater unit.

  • Page 14: Installing And Earthing Antennas

    You must connect an antenna to each 105 module using the SMA connector at the top of the enclosure. ELPRO recommends carefully taping the connections between the antenna and coaxial cable to prevent moisture ingress. Moisture ingress in the coaxial cable is a common cause of radio system problem as it greatly increases the radio losses.
