The typical system configuration comprises an omnidirectional array antenna featuring 6–10 dBd gain, installed at or above 20 m from ground level, and fed by the SLR 5000 Series Repeater through a combiner characterized by a typical 3 dB transmission loss, and a 30 m 7/8”...

    Appendix F : MOTOTRBO Repeater – EME ASSESSMENT Exposure at Ground Level Since the antenna installation height above ground level in the typical system configuration (20 m) is larger than either of the compliance distances determined in Exposure in Front of the Antenna on page 158, the EME exposure at ground level is always compliant with the exposure limits defined in the ICNIRP guidelines.
