ANTENNA MOUNTING BASE ASSEMBLY AND SYSTEM

摘要

An antenna mounting base assembly (1) is provided comprising a base (2) adapted to be secured to a vehicle body, a coiled spring support section (4) secured at one of its ends to the base and operatively supporting at its other end an antenna (12). The mounting base assembly has fixed to such other end of the coiled spring support section contact means (7) adapted to electrically connect an antenna conductor (13) passing into the spring support to a contact (10) on a lower end of an antenna whip. Coupling means (8, 11) are provided, typically in the form of a screw threaded spigot and socket for releasably attaching such antenna whip to the coiled spring support section. The invention also provides a vehicle antenna system in which a plurality of vehicles (21) are each provided with such an antenna mounting base assembly (1) so that an appropriate one of a selection of different antenna whips (17a and 17b, 18, 19, 21) may be coupled to a particular base for serving a particular purpose.
