EL定位的方法有三种,如图9(a)、(b)、(c)所示。天线调试中A_L和E_L确定后还需微调,以达到图、声俱佳的效果。现给出的我国4个直辖市,28个省会所在地接收亚太地区上空11个主要电视卫星的A_L和E_L(见表3)值,表中乌鲁木齐接收泛美2号卫星
There are three ways to locate an EL, as shown in Figure 9 (a), (b) and (c). Antenna debugging A_L and E_L after the need to fine-tune to achieve the figure, sound superb effect. Presently, the four major municipalities directly under the Central Government in China and 28 provincial capitals are receiving the A_L and E_L values (see Table 3) of 11 major television and satellite satellites in the Asia-Pacific region. In the table, Urumqi receives Pan-American satellite No. 2
