I live in India, Bangalore. I have an Airtel Huawei B310s-927 4G router. Since the network coverage in my area is very bad, I want to improve the 4G signal strength by using an antenna. But what antenna should I use? I tried searching elsewhere and found I can use an "SMA male" antenna, but what specifications Mhz? Can I buy a 900MHz SMA Male antenna?

Following is the instruction page of the router next to the router next to a USB drive for size.

  • Product recommendation questions are off-topic. Just make sure that you're asking about specifications and all is well. – isherwood Sep 12 '17 at 19:22

    This is what a google search of "India 4G Frequency" gave. Currently in INDIA, 4G LTE band-40 having 2300 to 2400 MHz (TD-LTE) frequency range is active (online) and offered by the operators in indian territory. – vini_i Sep 12 '17 at 19:30
