Your USB modem's tiny built-in antenna is doing its best, but the signal just won't hold past the kitchen window. This 510mm SMA-to-induction plug adaptor lets you clip an external 3G or 4G antenna to the window frame and actually get a usable connection. Plug it in, stick the antenna where you get bars, and stop refreshing the page. No soldering, no config — just a solid cable between your modem and the antenna that works
