Abstract

An apparatus for communicating a signal downhole includes a downhole pipe configured to be coupled to another downhole pipe and a protection tube secured to the downhole pipe. A transmission line is disposed in the protection tube and configured to communicate the signal. A communication device is disposed in the downhole pipe and configured to communicate the signal to another downhole pipe. An end of the transmission line is configured to be axially movable with respect to the downhole pipe in order to have the end of the transmission line extending from the protection tube to establish a connection between the transmission line and the communication device.
