The Nokia 20 GSM Connectivity Terminal is equipped with a removable dual-band antenna. It is also possible to use an external antenna with a standard FME connector. Nokia provides a special cable as an adapter between the Nokia 20 and FME connectors (accessory). For example, when the Terminal is situated inside the application module, which is made of metal, the antenna can be located outside of the module using an external antenna cable. In cases, when the field intensity is too weak, an antenna can be situated separately from the application module.
