A collet for multiple wire elements is disclosed. In an example, the collet has a body made of a polymeric material and extends along a central axis from a first end to a second end. The body defines a first passageway extending axially through the body, the first passageway in communication with the environment via a first insertion opening extending along an entire length of the first passageway. The body defines a second passageway extending axially through the body and in communication with the environment along an entire length of the second passageway via a second insertion opening, the second passageway spaced circumferentially from the first passageway. When installed, the collet frictionally engages wire elements when a first wire element is seated in the first passageway and a second wire element is seated in the second passageway.

An antenna module configured for use on an underwater vehicle is disclosed. The antenna module includes an array of spiral antennas fabricated on a multi-layer substrate that provides wide-band RF communication with direction finding (DF) capability. The antenna module can also include other antennas fabricated on the same multi-layer substrate, such as one or more global positioning system (GPS) receivers, an ultra-high frequency/very-high frequency (UHV/VHF) antenna, or one or more iridium antennas. The antenna module may further include a water-proof housing that is coupled to the outside hull of an undersea vehicle via a coupling mechanism. The coupling mechanism allows the antenna module to rotate between a stowed position against the hull and a deployed position that extends the antennas out away from the undersea vehicle. The antenna module is curved or flexible so it can stow against a corresponding curved hull of the undersea vehicle.
