WebA halo antenna, or halo, is a center-fed 1 2 wavelength dipole antenna, which has been bent into a circle, with a break directly opposite the feed point. The dipole ends are close, but do not touch, and may be widened to form an air capacitor, whose spacing is used to adjust the antenna's resonant frequency. WebIf you use a "complete" antenna like a dipole or a ground plane (that is, one that doesn't require your feedline to connect to ground), you don't need a RF ground, as long as you keep common-mode currents off your feedline. ... the 8-foot buried pole won't work.
