A UHF/VHF/FM antenna consisting of two elongated octagonal elements formed individually from ¼″ O.D. (Outer Dimension) flexible copper tubing, interlaced with each other before coupling of the open tubing ends, then concentrically aligned perpendicular to each other, and soldered at a interlacing cross points. Signals received by the interlaced elements are directed to a 300-75 ohm transformer balun through two bare 12-guage copper wires, each bent approximately 90°, then soldered to the mid-points of adjacent element short sides and perpendicular element cross points. |

1. An antenna having two loop elements, each fabricated from approximately 60″ of ¼″ copper tubing formed into elongated octagons through rounded 45° bends applied at approximately the 2″, 20″, 24″, 28″, 32″, 50″, 54″, and 58″ marks, that are interlaced and aligned perpendicularly and concentrically in the same plane before coupling of the tubing ends, then further connected by two approximately 24″ lengths of bare 12-gauge copper wire, each bent approximately 90° at their centers, and fastened along the mid-line of said elements to their respective transverse and far end segments, such that an approximate ½″ gap remains between the 90° wire bend points at the center of the antenna for attaching a balun. |
