EMERGENCY SERVICE ANTENNA
MULTIFUNCTION MiMo ANTENNAThe Emergency Service antenna has a compact OEM style shark fin housing that contains 2x2 MiMo antenna
function for 4G/3G/2G and an active antenna for GPS/Galileo with 26 dB gain LNA. In addition, there is anintegral stud mount for an external antenna whip that can support a range of VHF, UHF or 700/800MHz
antennas. A blanking cover is supplied for when an external whip is not required. A further version ofEmergency Service antenna is available that adds 2x2 MiMo antenna function for 2.4/5.8GHz WiFi.
The antenna’s shark fin style design provides multiple antenna functions while remaining discreet and issuitable for public safety (overt/covert), industrial and transport applications where a cost effective, efficientand robust antenna is essential. Requiring only a single hole mounting, the Emergency Service antenna
reduces vehicle damage, installation time & cost and visual impact whilst protecting a vehicle’s resale value.
