An animal training apparatus including an electrical conductor embedded within a flexible member, and a housing having a through-opening for receiving the electrical conductor therethrough. The flexible member is molded around the electrical conductor and the antenna, while the electrical conductor is positioned such that it extends into the housing through the through-opening. As a result of the molding process, the flexible member shields the housing through-opening, discouraging substances such as water from accessing the interior of the housing via the through-opening.
