Editing Direction finding (section)

====Yagi antenna for higher frequencies====
The [[Yagi antenna|Yagi-Uda antenna]] is familiar as the common [[VHF]] or [[Ultra high frequency|UHF]] [[television]] aerial. A Yagi antenna uses multiple dipole elements, which include "reflector" and "director" dipole elements. The "reflector" is the longest dipole element and blocks nearly all the signal coming from behind it, hence a Yagi has no front vs. back directional ambiguity: The maximum signal only occurs when the narrowest end of the Yagi is aimed in the direction from which the radio waves are arriving. With a sufficient number of shorter "director" elements, a Yagi's maximum direction can be made to approach the sharpness of a small loop's null. {{citation needed|date=October 2023}}
