Would you like to be better prepared?
Over the next few issues of this newsletter, this columnis going to present some information that you probably already know, but,like most of us, have not gotten around to doing anything about it. Whenthis series is completed, you will have created a communications "GO-KIT".A bag full of goodies that you would not normally be using, but, has beenprepared, tested, and packaged to GO with you anywhere, quickly. With simpletools and basic skills, you will be able to create the contents of theGO-KIT to be more prepared for effective emergency communications.

This wire is available at almostevery hardware, drug store, and other stores that carry such items as telephoneextension cords.
In the diagram below you will see the construction detailsof the antenna.
