Abstract: A casing hanger (920) positioned in a wellhead (910) has an electrical connector (940) which can align with a connection port (912) in the wellhead (910) to allow downhole power and signals communication to be maintained without removing any wellhead valve structure. Alignment wedges can be used to ensure the port (912) and the electrical connector's opening (924) are aligned. The opening (924) can be covered by a debris seal (960) for protection during installation. Also disclosed is an electromagnetic casing string antenna system for two-way communication downhole (see figures 10a-c). Antenna cylinders (1010, figure 10a) can be mounted coaxially on to casing joints (1020, figure 10a) and can be both transmitters and receivers. Also disclosed is an antenna module with sealed induction interface (see figures 13-15). Antenna modules (1320, figure 13) can be mounted in a drill collar (1310, figure 13). The modules are sealed by an epoxy surface (1364, figure 14) which is ground flush to an inside surface (1362, figure 14). The wellhead electrical connector arrangement, casing string antenna system and sealed antenna module can all be used together and are intended to be used in conjunction with a downhole deployment valve (DDV).
