Abstract: A termination assembly is disclosed providing a substantially watertight, yet field serviceable interface to a plurality of electrical splices. The termination assembly includes a housing having an anchor portion for receiving and fixing a multi-transmission line cable therein, a ported sleeve for cradling the transmission lines, and a shell for providing field access to the splices between the transmission line in the interior of the housing. A resinous epoxy, together with O-ring seals and heat shrink tubing provide redundant protection against the invasion of water into the housing along the transmission lines.
