More and more devices for WLAN do not consider that it is a wireless technology where the antenna is a highly important part of the signal quality. With an antenna can send and receive clean signals amplifies weak signals better. This pigtail I have repeatedly installed, soldered in equipment to the pins of the antenna output and a gain antenna mounted externally. By standardized connector can draw on a range of powerful antennas and replacing jederzit. These few euros should be poorly sparking wireless devices treat.
