Environmental
 Designed to withstand ejection from fast jet and will operateover the temperature range -20°C to +55°C. Designed to meet the environmental standards and condiftions of STANAG 7007
and DEF STAN 00-35 relevant to this type of equipment.
Antenna(RF)
 Three frequency antenna may be mounted directly to the beacon or remote through an extension for operation in a life jacket or dinghy.
Antenna(GPS)
 External to the beacon for mounting on the users shoulder or otherconvenient location. Permits maximum visibility of the GPS Satellite constellation to minimise the time taken for position acquisition.
