论文摘要
通过测量要求确定HF-Antenna的效率是一个复杂的程序，涉及昂贵的设备，校准仪器的野外强度。在本文中，我们评估了一种简单，廉价的方法，以确定天线相对A参考天线的相对效率。该方法使用弱信号传播报告基因（WSPR）网络，该网络遍布世界各地。这些接收器报告了接收的信号信号与WSPR.NET数据库的估计信号与噪声比率，在该数据库中可以实时检索数据（几乎）。在本文中，我们分析该方法，估计其准确性并讨论优势和局限性。提出了一些初步测量结果。
Determining the efficiency of an HF-antenna by measurements requires is a complex procedure involving expensive equipment, calibrated instruments for field strengths. In this paper we evaluate a simple, inexpensive method to determine the relative efficiency of an antenna relative a reference antenna. The method uses the Weak Signal Propagation Reporter(WSPR) network of receivers that are located all over the world. These receivers report the estimated signal-to-noise ratio of received beacon signals to the WSPR.net database where the data can be retrieved (almost) in real time. In the paper we analyze the method, estimate its accuracy and discuss advantages and limitations. Some preliminary measurement results are presented.
