Methods and apparatus for a modular utility connection system according to various aspects of the present invention include one or more utilities routed within a housing. The housing connects each of the routed utilities to a suitable preexisting source. The housing may also be linkably connected to one or more additional housings such that only a single housing need be connected to the preexisting source. The housing also comprises access points to each of the utilities allowing a user access to the utility via the housing rather than connecting directly to the source.

A portable dog-training transmitter unit for controlling remote collar-mounted receiver/stimulus units includes first, second, and third switches for causing corresponding transmitted stimulus control signals to be recognized by corresponding first, second, or third receiver/stimulus units. A multiple-position switch sets the use of transmitted codes that control the amplitudes of stimulus signals produced by the recognizing receiver/stimulus unit. The transmitter unit is supported in a holster that is pivotally supported by a belt clip through the use of a pivot pin that is pivotally retained in a receiving slot of the belt clip. The transmitter unit includes a controller which polls the states of the various switches to produce a digital signal that is shaped by a buffer circuit, FM modulated, preamplified, and coupled by a simplified matching network to the input of a power amplifier. A single pi matching network is coupled to match an output of the power amplifier to an antenna of the transmitter unit.
