4.4 Connection of external antenna (optional)

In the top part of the TEL50.GSM, there is an RF female SMA connector that is normally connected to the specially supplied
stilo antenna. Ensure that the antenna connector is securely fastened.
In some operating conditions, the stilo antenna does not permit optimum reception of the RF signal and, for this reason, the
TEL50.GSM can also be used with a high gain directive or omnidirectional external antenna (optional). If this is necessary,
remove the stilo antenna connector and connect the external antenna one.
