On the satellite side, advances in antenna design, beam steering and power management have increased signal directivity and strength.—Charlotte Kiang, Forbes.com, 24 Feb. 2026 In the Narrow directivity mode, the three full-ranges are used from 200 Hz to 4,000 Hz, so driver output favors a listener sitting in front of the speakers, without the interference of side and rear wall reflections.—Robert Ross, Robb Report, 4 May 2021 Brand New Test Frontier The mmWave frequencies demand more sophisticated RF parametric measurements for signal gain, directivity, beamwidth and antenna efficiency.—IEEE Spectrum, 3 Dec. 2018 His idea was to pick up that signal with a portable radio receiver using the receiver’s loopstick antenna for directivity.—Andrew Freeman, Outside Online, 21 May 2012
