The Samsung Galaxy S2 has a small gold RF connector which is can be accessed by taking off the back cover. This patch lead is used on a daily basis by staff to increase the speed and reliability of mobile broadband internet, and to extend coverage of the phone when travelling to remote regions of Australia. An external antenna produces an immediate increase in signal which results in faster mobile internet access, much longer usable range from a cell tower, improves voice quality and reduces call dropouts. We sell replacement and pre-drilled back covers for access to the RF port without the cover being removed.
What does a patch lead do?Most antenna cables terminate with a standard connection, most commonly a female 'FME' connector. To plug an antenna into your phone or wireless modem, you need a short cable that acts as a conversion from the FME connector to the device-specific connector that will plug into the antenna port on your device. The antenna port on the Samsung Galaxy S2 was installed for testing purposes, but is fine to connect and use an external antenna. The use of cheap imported leads, and inserting the lead at an incorrect angle can damage the phones RF port by permanently activating the external antenna - please be very careful when inserting and be cautious of inexperienced sellers. It is also very important that the lead never be pulled sideways, or a force never be applied across the lead - all patch leads are extremely vulnerable to shearing force and can damage both the lead and the internal connector.
