The Front Cover
On the frontcover is shown the Northstar modular tower; this is a tower that, once installed, looks just like the conventional cousin from which it has evolved. The tower is a modular, field-assembled panel design. With this design, tower panels can be added to increase the tower diameter and height. On page 7 you will find the article about the concept.
