Abstract

PURPOSE:To improve F/B by providing a phase correcting circuit in a phase-different feeding device for two dipoles. CONSTITUTION:Phase correcting circuit 10, provided at the feeding point of the rear dipole, provides parallel resonance over a low channel (approximately 100MHz) or series resonance over a high channel (approximately 190MHz). Therefore, the attenuation quantity and phase quantity are both nearly ''0'' over low channels of 90-110MHz and phase corrections are made only over high channels. Phase correcting circuit 20, provided at the feeding point of the front dipole, is made to start series resonance at a point of 300 or more MHz and makes phase corrections of about 10 deg.-20 deg..
