ABSTRACT:
For a vehicle which sometimes requires two-way radio communications but which sometimes requires an ordinary appearance, for example an unmarked law enforcement vehicle which could be compromised by the conspicuousness of a conventional communications antenna and associated external mounting hardware, this antenna system provides an external antenna rod which is readily deployable and removable from within the vehicle. The novel mounting hardware is highly inconspicuous since its exposed area is very small and is made flush with the surrounding vehicle body surface. In the mounting assembly, an insulated bushing, carrying a socket having a contact sleeve, has a small aperture in line with the contact sleeve, forming a passageway through the vehicle body through which the external antenna rod may be deployed. Alternatively, an internal antenna rod may be readily deployed in the same mounting assembly to project inwardly, enabling covert limited range communications. The internal antenna rod is fitted with a protective ball at the end to avoid risk of injury. The mounting assembly is easily installed in a vehicle, requiring only one small hole through the body.
