All you need is two rabbit ear antennas from Radio Shack, two CATV baluns, four feet of 3/4" CPVC pipe with one tee, and a bit of time. A Portable Quad for 2 Meters by WA9GDZ/6.
How High Should My HexBeam Antenna Be? - YouTube
WebIn the last few years, there has been growing interest in employing metamaterials (MTMs) to enhance antenna gain. In this paper we proposed a novel structure of planar folded-line left-handed metamaterial (FL-LHM) and applied it to improve the gain of three 5.8 GHz microstrip antenna types: a circularly polarized patch antenna, an antenna array, and a … Web29 de jul. de 2024 · Download this article in .PDF format.
