Administrative Regulations on the Establishment of Radio and TV Broadcast Station Article 2
The terms of these Regulations are defined as follows:1. Field Strength: means radio wave strength in μV/m or dBμV/m tested by Standard Half-wave dipole Antenna at a height of 2m beyond the induction filed of antenna（a distance from one wavelength of antenna at least）.2. Ground Wave: Propagation of radio wave can be briefly classified as directed wave, reflected wave, refracted wave, diffracted wave, surface wave and scattered wave, where radio wave propagating along the surface of the earth is called Surface Wave and referred to as Ground Wave. Radio wave propagating from the reflection of the ionosphere is called Sky Wave. Directed Wave, Surface Reflected Wave and Ground Wave are jointly called On-ground Wave.3. Relay Station: means station that doesn’t have the equipment to produce a program and uses a repeater system to receive programs from main station as well as broadcasts them.4. Shared Metal Tower: a tower of metal construction on which radio transmission antennas of two or more radio and/or television stations are installed.5. Wireless radio station: a station that broadcasts voice-modulated signals in the form of radio waves for public listening; by the way of modulation, there are amplitude-modulated and frequency-modulated radio stations.6. Wireless television station: a station that broadcasts video-modulated signals in the form of radio waves for public listening and viewing.7. Transmission power of transmitter: the average radio power from the output side of a transmitter to the input side of a connected antenna in W or kW.
中文原文 無線廣播電視電臺設置使用管理辦法（109.11.24 訂定）第2條
本辦法用詞定義如下：
一、電場強度：指在天線感應場外（至少距天線一個波長距離），以高二公尺標準半波偶極天線所測得之無線電波強度，以微伏特／公尺（μV/m）或以分貝微伏特／公尺（dBμV/m）為單位。
二、地波：電波之傳播方式可概略分為直射波、反射波、折射波、繞射波、表面波及散射波等六種，其中沿地球表面傳播的無線電波稱為地表波，簡稱地波。
經由電離層反射傳播的無線電波稱為天波。
直射波、地表反射波及地波合稱為地上波。
三、轉播站：指本身未具有製作節目設備而利用中繼系統接收主臺節目，同時將其轉播之電臺。
四、共同鐵塔：指二以上之廣播或電視電臺共同附掛發射天線之鐵塔。
五、無線廣播電臺：指以無線電進行聲音調變訊號之播送，以供公眾收聽之電臺。
依調變方式分為調幅廣播電臺、調頻廣播電臺。
六、無線電視電臺：指以無線電進行視訊調變訊號之播送，以供公眾收視、聽之電臺。
七、發射機發射功率：指發射機輸出端於連接天線輸入端處之射頻平均功率，以瓦（W）或千瓦（kW）為單位。
