Anything else I need to know?
All PCBs are supplied with a quad band stub antenna and a PCB to aerial connector cable (~15cm long). Antennas should be mounted outside of metallic enclosures. The PCB connector is a U.FL connector and the aerial connector is a standard GSM SMA connector shown below (should an extension cable be required).
Our optional sticky backed antenna makes installation quick and simple however this can only be mounted on non-metallic thin surfaces. Various antennas are available from our wesbite - please see 'Accessories'.
When deciding on which network to use we recommend that you search on the network provider home page to ensure you will receive a good signal in your geographic location. Please note GSM products do not work with 3G only networks such as 'Three'.
