  • In this pictorial, we've put a 12dBi glass mounted antenna in the window and connected it to the S4 using our patch lead

  • 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.

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 S4 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. 


Where do I plug my patch lead in?


  • The Telstra Samsung Galaxy S4 4G has two external antenna ports L1 and R1

  • When connecting your Galaxy S4 to an external 4G antenna it's important to only use the L1 port

  • The R1 port is used to improve 3G services

  • These ports are auxiliary ports, not switching connectors, the internal antenna will remain active and the device will choose based on which receives stronger signal.
