Abstract: A communication housing for devices external to a solid marine seismic cable, especially for level control devices, comprises an upper housing half and a lower housing half, coupled together around the cable. The upper housing half includes a plurality of wells, for example three wells, each adapted to receive a communication coil. The lower housing half has no such wells. The communication coils are wound in series to reinforce the signal strength of the communication signal. The communication coils are preferably formed to two segments, joined together at a flexible joint to reduce the likelihood of breakage of the coil core as the cable is wound onto a take up reel aboard the exploration vessel.
