Installing the Device2.5.3 Connecting LTE AntennasCAUTIONConfiguration hazard – risk of reduced performance.Each antenna and connecting cable must have a nominal impedance of 50 Ω with areturn loss of better than 10 dB across each frequency band. If the nominal imped-ance is different, Radio Frequency (RF) performance will be reduced.NOTICEThe antenna installation must be as per Article 810 of the National Electric Code(NEC). Specifically, the grounding conductor must not be less than 10 AWG (Cu).The scheme should be either:• In accordance with UL 96 and 96A Lightning Protection Components and Instal-lation Requirements for Lightning Protection Systems (LPS)• Tested in accordance with UL 50 and UL 497NOTICEA Radio Frequency (RF) site survey is recommended prior to any installation to helpdetermine the best location for the LTE antennas. For assistance, contact a SiemensSales representative.NOTICEThe cellular modem supports SISO (Single Input Single Output) and MIMO (MultipleInput Multiple Output) modes. At minimum, a single antenna connected to the LTEMAIN port is required for SISO mode and to support lower generation wireless stan-dards, such as GSM or EDGE. A separate diversity (secondary) antenna is required forMIMO performance.NOTICEFor mobile and fixed operating configurations, in accordance with R&TTE Directive1999/5/EC, the maximum antenna gain is 3 dBi for 900 MHz, 1800 MHz, 2100 MHzand 2600 MHz.NOTICEFor mobile and fixed operating configurations, in accordance with FCC 47 CFR, sec-tion 2.1091, the antenna gain, including cable loss must not exceed:• 6.0 dBi at 700 MHz• 3.0 dBi at 800/850 MHz• 6.0 dBi at 1700 MHz• 3.0 dBi at 1900 MHzUnder no conditions may an antenna gain be used that would exceed the ERP and/orEIRP power limits specified in FCC 47 CFR Parts 22, 24, 27 and 90.NoteFor technical specifications, refer to "Cellular Modem Specifications (Page 36)".RUGGEDCOM RX1400Installation Manual, 09/2019, C79000-G8976-1103-13 17
