BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to tall tower and building arrangements where used for structural and electronic support of antenna. Even more particularly, the present invention relates to an improved antenna tower and support apparatus that features an improved configuration of multiple equipment rooms, multiple sets of antenna cable, and multiple sets of antennae at different elevations on a tower.

2. General Background of the Invention

Very tall towers are typically used to support one or more antennae at desired elevational positions. One of the most common usages of such a tower is in the cellular telephone industry. Other examples of such antenna supporting towers include radio, pagers, television, and two-way radio.

One of the means of defraying the expense of constructing such a tall antenna supporting tower is to provide multiple users with multiple electronic support/equipment rooms. This provision of multiple rooms and multiple sets of antenna associated with a single tower can present security problems. It is to this problem that the present invention is directed.

Numerous patents have issued that are directed to very tall towers which support either a single antenna or multiple antennae. Examples of such patents are contained in the following table:
