Abstract
An improved power actuated antenna installation, particularly for automotive vehicles, of the type including a mast jacket rigidly attached to body structure of the vehicle, a telescoping antenna disposed on the mast jacket, a power actuator disposed on an L-shaped housing with a first leg parallel to the mast jacket and a second leg below the mast jacket, and a flexible drive element projecting into the mast jacket through a guide bushing at the lower end thereof for attachment to the antenna and into the second leg of the housing for attachment to the actuator, the improvement residing in the provision of elastomeric grommets between a pair of pins on the mast jacket and a pair of rigid arms on the first leg of the housing and in the provision of a combination seal and grommet between the drive element and housing generally immediately below the mast jacket, the grommets and the combination seal and grommet effecting resilient support of the actuator on the mast jacket in a manner discouraging transmission of actuator vibration to the supporting body structure.
