What is GSM antenna?
GSM Antenna is one kind of Antenna to transmit GSM signal at specified frequency 850, 900, 1800, 1900, 2100MHz. 2100MHz is separated into UMTS (Universal Mobile Telecommunications System) frequency band for 3G, and other frequencies are separated into 2G. GSM Coverage Maps and Roaming Information.
How do I choose a mobile phone antenna?
Mobile antennas can be measured in dBi or dBd units. If you’re converting between the two, subtract the 2.15 from the dBi to find the equivalent dBd. For example, a 4.0 dB is equal to a 1.85 dBd. A general rule of thumb for choosing a new antenna is the bigger, the better.
