Samsung Galaxy S4 Patch Lead i9500/i9505/i9295 Active
- Converts from phone connection to Antenna (FME) connector
- High quality Samsung RF connector with 30cm of RG174 cable
- Boost signal strength and coverage of your handset
- Improve your mobile internet speed and reduce call dropouts.

The Samsung Galaxy S4 has two small gold RF connectors which can be accessed by taking off the back cover. This patch lead is used on a daily basis by staff (on their S2, S3, and S4 models) 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.

This patch lead is not suitable for the S4 Mini - the S4 Mini cannot take a patch lead.

Check out how easy it is to dramatically improve indoor 4G coverage on a Telstra Next-G Samsung Galaxy S4. In this demonstration we've put a 12dBi glass mounted antenna in the window and connected it to the S4 using our patch lead.

Please watch this space - we'll be uploading our S4 video shortly.

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.
