- If the GSM signal is too weak:
- add an RF extension cable with SMA connector (max. 2 meters) + 1 adhesive support;
- use a high-gain antenna (max. 10 meters of cable)
- Use the antenna supplied with the device if the GSM signal is sufficiently strong in the selected location.
- If the signal is too weak, move the original antenna out of the cabinet; add an RF extension cable with SMA connector (max. 2 meters) + 1 adhesive support to hold the antenna.
- If the signal quality is still too weak, install a high-gain antenna with a maximum of 10 meters of cable; the antenna can, for example, be moved outside or to other floors to improve signal reception. Do not use a cable longer than 15 meters as this degrades reception quality. Follow general and antenna mounting instructions in the data sheet.
