Back in the early days of the mobile phone, there was no impressive new internal antenna system; What there was however were those retractable antennas that looked every bit as curious as you remember. Enter the Linkase Pro LTE case for the iPhone and just like its previous model, it boosts your LTE data radio.
Using a sliver of an antenna which can be extended in time of extreme need for LTE, it says that the case will also save you battery because your phone doesn’t need to constantly switch between Edge, 3G and LTE. Not sure how effective this is, but all i know is that some of us definitely need one to improve OVERALL cellular signal in Malaysia. The Linkase Pro LTE case is currently a prototype and is seeking funding on IndieGoGo
