A slow connection directly influences your online experience. Generally the outdoor signal is about -20db stronger than the signal indoors. Indoor performance is therefore greatly compromised. By mounting a fixed external antenna and coupling it via the cable to the 3G/4G device, performance will be greatly improved.This is done by attaching the antenna cable to the router via a fly lead (30cm cable and device specific connector) or generic adapter pad (ADPT-24).Below is a video that shows the difference in speed tests with and without outdoor antennas. There are a variety of speed tests on our YouTube channel where we test different modems and routers with our antennas.
