Apparatus and methodology for radio utility meter reading processing of data acquisition for use with an automatic billing system involves a utility meter transmitter antenna system installed at or near ground level. An RF utility meter communication apparatus transmits utility meter data to a remote utility meter data collection unit from an underground pit box. The pit box includes a utility meter and has a generally ground level pit lid with an opening therethrough. An antenna element has an upper member extending at least partly through such pit lid opening. A depending base of the antenna element extends from the upper element and passes through the pit lid opening into the underground pit box. The depending antenna element is capacitively coupled or provided with some other form of non-mechanical coupling to the output of an RF transmitter also included within the pit box. The antenna element components are nested for ease of attachment to or removal from a pit lid, with a rotatable threaded nut received about a depending antenna element for drawing tight against the underside of the pit lid, with an upper antenna element received above such pit lid. An antenna element may be directly coupled with a metallic pit lid so that such metallic pit lid functions as part of the antenna. Alternative embodiments may be provided for structure of the antenna element, so as to minimize the structure and components needed for removably securing or installing the antenna arrangement, supported on the removable pit lit of a conventional pit box.
