Figure 6 - Antenna position
Extension Antenna
An extension antenna can be used in the event that the Receive Signal strength at the location is
inadequate, and changing locations is not an option. Two high gain antennas are available:
1. Aerial (short) – AO100 External base antenna
2. Aerial (long) – BA900-5 High gain antenna (1.2m white stick)
Each antenna is supplied with a 5 m RG 58 coaxial cable terminated by a female FME connector. A
20 cm male FME to male MMCX flying lead is used to terminate the antenna on the Redcare Secure
unit GSM module.
A 10 m low-loss URM 76 coaxial cable is available should the cable run to the antenna need to be
extended. This cable is equipped with a male FME connector at one end and a female at the other.
