The external magmount antenna must be used with the Nokia XRM-1 antenna connection cable for connection to the Nokia 30 terminal.

The external magmount antenna improves the GSM connectivity of the Nokia 30 terminal.

The standard cable length is 3m, but longer length cable is available on request, although signal strength of the Nokia 30 terminal will not be improved is the cable length is too long.

The external antenna is ideal when using the Nokia 30 terminal in an enclosed area, like the back of a car or van, and an external antenna is then required to improve/maintain a GSM connection on the Nokia 30 terminal.
