All three crossbars are equipped with gangways that carry additional smaller antennas.

In the 1990s an additional antenna was added bringing the height to 210 metres.

An additional four antennas placed some distance behind the transmitting array.

The additional antennas can allow reuse of the same frequency over multiple paths, increasing the potential throughput.

Considering antenna diversity, in many systems additional antennas may be expensive or impractical at the remote or even at the base station.

Amos 1 and Amos 2 are placed in proximity to a create common location, which enables satellite users to increase user abilities without additional antennas.

Each additional antenna added another element of space and because of that, additional capacity.

For Phase 2, seven additional antennae will be added to extend the longest baselines to about 20 km.

At the center is a modular, six-sided box containing the craft's electronics and bristling with additional antennas.

A cosmetic improvement on the tower, the lighthouse will also let Highpoint install additional antennas.
