Although nearly a century has passed since Marconi's first demonstrations of radio communication, there is still research and experiment to be carried out in the filed of antenna design and behaviour. The aim of the experimenter will be to make a measurement or confirm a principle, and this can be done with relatively fragile. short-life apparatus. Because of this, devices described in this book make liberal use of cardboard, coking foil, plastic bottles, cat food tins,etc. These materials are, in general, cheap to obtain and easily worked with simple tools, encouraging the trial-and error philosophy which leads to innovation and discovery. Although primarily a practical book with text closely supported by diagrams, some formulae which can be used by straightforward substitution and some simple graphs have also been included.
