TL;DR: The paper focuses on the comparison of the radiation pattern and presents not only the measurement data obtained at the facilities, but also investigates several procedures for comparing these data, which includes various definitions of pattern difference and statistical measures as well as a reference pattern.

TL;DR: In this paper, three possible approaches for definition of a highly accurate reference pattern of a reference antenna are described and their pros and contras are discussed, and a dedicated measurement campaign was planned and carried out in 2007-2008 for the definition of the VAST12 antenna.

TL;DR: The VAST12 antenna and a dedicated measurement campaign carried out in 2007–2008 for the definition of its accurate reference pattern are described and the potential use of the reference pattern for benchmarking of antenna measurement facilities is outlined.

TL;DR: In this paper , a setting-free double-ended fault location method for power transmission line is proposed using both end voltage and current measurements, which can locate the fault within two-tower span distance (~300m) which is comparable with traveling wave-based method that requires 1000 times higher sampling rate, high-cost hardware, more complex commissioning and settings.

TL;DR: In this article, uncertainties for calibration of SGH from measured directivity and estimated loss have been shown together with uncertainties for the gain transfer method on a compact antenna test range on a test range.
