FCC F(50,50) TV broadcasting signal strength variation

This data is the Federal Communication Commission (FCC) F(50,50) signal strength variation curves for the Very High Frequency (VHF) Channel 7-13 and the Ultra High Frequency (UHF) Channel 14-69. The signal strength for both curves is in dBuV/m for an Effective Radiated Power (ERP) per dipole of 1 kW. All data are based on a 9 m mobile antenna height measurement for 30 m to 600 m antenna heights within a transmitter-receiver separation ranging from 1.5 km to 100 km.The .xlsx file is separated into three sheets. The first and second sheets have the same structure, where the first column is the transmitter-receiver separation (d) in kilometers. The first-row heading is the transmitter antenna height (Tx) in meters, and the signal strength readings are from the second column-second row to the fourteenth column. All the data are readings directly made from the F(50,50) curves. Converting the signal strength variation into a loss (dB), we proposed a propagation loss model given by the expression L = A + C1 d + C2 log10(d). The third sheet provides the coefficient C1 and C2 variations for the respective VHF and UHF bands.

本数据集为联邦通信委员会（FCC）针对甚高频（VHF）频道7-13和超高频（UHF）频道14-69的F(50,50)信号强度变化曲线。两条曲线的信号强度均以dBuV/m为单位，对应于每偶极子1千瓦的有效全向辐射功率（ERP）。所有数据均基于9米移动天线高度，在30米至600米的天线高度范围内，以及发射台与接收台之间距离从1.5公里至100公里的测量结果。.xlsx文件分为三个工作表。前两个工作表结构相同，其中第一列为发射台与接收台之间的距离（d）单位为公里。第一行标题为发射天线高度（Tx）单位为米，信号强度读数从第二列第二行至第十四列。所有数据均为直接从F(50,50)曲线中读取。将信号强度变化转换为损耗（dB）后，我们提出了一个由表达式L = A + C1d + C2log10(d)给出的传播损耗模型。第三个工作表提供了相应VHF和UHF频段的系数C1和C2的变化。
