The core of a wire carries no radio fre-quency current and performs no electricalservice, because of this radio frequency phe-nomena called skin effect. The core maytherefore be made to perform a greater me-chanical duty. Hence the ideal wire forradio antenna should have a core of greatstrength (steel) and an outer covering of highconductivity (copper).</i><br><b>Text Appearing After Image:</b><br><i>CHAPTER XII GROUND CONNECTIONS Common Faults of Aerials—How to Put a Metal Roof to Use—Proper Place for the Lead-in—Uses of the Counterpoise If you have not a good aerial and yourground connections are defective you cannotexpect to be able to sit in on the radio broad-casting concerts. The commonest faults with aerials are thatthey are too short and are not far enough fromthe ground. You cannot expect to be able topick up much with ten or fifteen feet of wirestrung near to the earth like a clothes-line. The aerial should be at least fifty feet clearof all obstructions if you are using a crystalset. Of course, if you have an audion detec-tor, then height is not so essential. However,even with a vacuum tube the aerial shouldnot be less than twenty-five feet above theground or roof. For receiving sets it is not necessary to use costly copper or bronze wire for your aeria). 78 AMATEUR RADIO 79 Galvanized iron wire, which may be boughtfor about four feet for a cent, is good enough.A</i><br><br><b>Note About Images</b><br></p>
