I recently purchased GSM module RB-Itb-01. I think I need an antenna because I am barely within 2G service and the module is not linking with the cell towers. The GSM documentation calls for AGSM-SMAF#085 or AGSM-SMAF#100; however, neither of those produce any results when searched on Robotshop.com. Please recommend a suitable antenna for RB-Itb-01.
Hi,
The Arduino & Raspberry Pi GSM/GPRS/SMS/DTMF Shield has a uFL connector. Therefore, you can probably use an Interface Cable SMA to U.FL with an SMA connector Antenna.
Please take a look at our Antennas section.
