I have a Verizon Samsung Galaxy S4, and during disassembly I noticed that it contains two antennas - one in the position as shown in this guide and one on the exact opposite side (colored light red). It too must be disconnected in the same fashion as the antenna in this guide. Removal and installation of both antennas was simple. As the guide suggests, I would recommend installing USB board and motherboard back in place prior to reinstall and routing of antenna wires. Excellent guide. Fixed my broken S4!
