Spring boot for a mobile antenna

摘要

A spring boot for use with an antenna comprises a cylindrical main body having an annular flange at the lower end thereof, and an annular rim at the upper end thereof. The flange has a plurality of mounting holes therethrough. The interior of the spring boot is hollow and is configured to match the shape of the antenna spring. When installed, the spring boot is fitted over the spring, and seated on an antenna mount, encircling the spring. Fasteners are installed through the mounting holes on the flange to affix the spring boot to corresponding bores in the mount. A washer is positioned atop the rim and is fixed between the antenna core and the spring. This configuration effectively constrains the spring boot between the core and the mount, so as to provide added damping to the antenna spring.

1. An antenna assembly comprising:
an antenna (12) having a core (14) mounted to a spring (16), and adapted to be secured to a vehicle by way of a mount (18), a spring boot (10) having an upper rim (24), a lower flange (22), and a hollow interior chamber (28) defined by an interior wall, and fitted over the spring and sitting on the mount with space between the interior wall and an exterior of the spring, and a washer (34), wherein the spring boot is fitted over the spring, the spring (16) is secured to the mount (18), the lower flange (22) is secured to the mount (18) with the spring boot (10) encircling the spring (16) in the interior chamber (28) and independent therefrom, and the core (14) is secured to the spring (16) sandwiching the washer (34) therebetween, the spring boot (10) will be constrained between the washer (34) and the mount (18), whereby to enhance the ability of the antenna (12) to absorb an impact without overstressing the spring (16) and provide additional damping to the spring.
