Solving the Lead-in Question

PROBABLY most radio — enthusiasts have at one time or another been confronted with the difficulty of getting the aerial down-lead into a room without drilling a hole in the woodwork of the window-frame, or similarly damaging the household property. Such a problem very often assumes serious proportions, especially when the household or property-owning "powers that be" resolutely refuse the enthusiastic amateur permission to bore a_ hole through the window frames. However, the problem can be solved in the following way: Procure a brass or copper strip about one foot long and half an inch wide. A strip of metal about 28 guage is quite suitable. Bore a hole at either end and fasten

on two small terminals. Next obtain a foot of rubber tubing of a diameter rather less than the width of the metal strip. Remove the screws from each end of the strip, and slip the tubing over, allowing about lin. to project at either end so as to expose the holes for the terminals. It is now a comparatively simple matter to fix this type of lead-in through the top of the window. The metal strip will be pressed to the shape of the window frame when the latter is closed. With this window lead-in in position, the aerial downlead is attached to the outer terminal and a lead from the inner terminal may be run to the set.
