My friend bought mobile broadband from "3". unfortunately she is in place with poor reception. I want to help her and I need to find some good, but not expensive antenna to increase signal. The usb modem is huawei e160. she want to spend about 20 quid, but if is not enough for good antenna she can go up to 40 quid. I try to find some, but is not so easy because of different sockets on the market. If someone bought it for the same reason, please tell me, where I can find it.
