Figure 2-46. Multiple Antennas Separation for locations 1-10
Figure 2-46 indicates the separation distances required for the various antennas used with an APX
8500 radio. Each "cross-hair" symbol represents a possible location, that is LOC of an antenna. The
recommendation is to locate them as close to the center of the roof and/or trunk as possible, without
interference with a lightbar. This picture is not drawn to scale.
For letters A, B, C, and D, the table indicates the EXACT distance for separation of the LMR
antennas.
For letters E, F, G, and H, the table indicates the maximum distance between the edge of the ground
plane and the accessory antenna (BT/WLAN, LTE or GPS) location.
NOTE:
• A minimum of 18 inch separation is required between lightbar and any roof mounted antennaH,
to prevent interference with the lightbar circuitry (see lightbar manufacturers installation
information).
• The LMR 700/800 antennaH should only be placed at LOC:2 or LOC:5.
• Standard LMR VHF and UHF antennaH should only be placed at LOC:1, LOC:3, LOC:4 and
LOC:6.
• 1/4 wave LMR VHF and UHF antennaH DQGDOO9+)DQG8+)DQWHQQDHWUDQVPLWWLQJDERYH
:should only be placed at LOC:1 and LOC:3 (i.e.roofonly) to ensure compliance with RF
Energy Exposure regulations.
• The VML antenna must be separated from any LMR antenna by at least 40 inches.
• The LTE Main and Diversity Antenna locations should be at LOC:9 and LOC:10 when the LMR
All-Band or LMR 700/800 narrow band antennaH are at LOC:2 (i.e LTE opposite location from
the LMR).
• The LTE Main and Diversity Antenna locations should be at LOC:7 and LOC:8 when the LMR
All-Band or LMR 700/800 narrow band antennas are at LOC:5 (i.e LTE opposite location from
the LMR).
• In some mobile installations that include an LTE modem, external filtering on the LMR portand/
or the LTE port may be needed to reduce interference. Contact your local MotorolaSolutions
Service Center for more information and for filter kit numbers (See Appendix forcontact info).
