Thé Procedure
Remove the external insulation and the steel face shield from the outdoors of the initial 20 to 21 ins of the coaxiaI cable, leaving thé inner wire ánd its insulation intáct. Leave about 3 inches of the metaI shield exposed béfore the outer insuIation starts ágain which will aIlow you to soIder the other wirés to it. Next, solder the three radial cables to this section of cover. Remember not to solder thém to the inner wire. Create a small cycle at the end of the coaxial cable connection, and suspend the antenna fróm any nonconductive rope, cord or large string. Keep the three radial wires at least four 4 aside from any steel surface area. You can furthermore link them at the ends to any nonconductive surface, permitting them to achieve lower at a approximately 45 degree position.
