Abstract: A retainer includes a base portion, a plurality of prongs, and a retention clip. The base portion has an inner bore engageable with a threaded stud extending from the mounting surface. The prongs extend outwardly from the base portion and are slidable into a bore of a device to be mounted to the mounting surface. The retention clip is formed by an outer distal end portion of the prongs and is configured to retain the device on the mounting surface by snap-locking onto the device when the device is slid onto the retainer. The prongs outer distal ends that are compressibly spaced apart from one another. In order to facilitate release of the device from the mounting surface, a pair of finger pads may be located at the outer distal ends of the prongs. The retainer is well-suited for mounting a telemetry antenna on a surface such as a ceiling and, in fact, can reduce antenna installation time by 75% when compare to prior known systems.
