This means that the SETI receiver was perched permanently above the Arecibo dish at the base of the aging line feed antenna.
也就是说SETI的接收器永久的占据着阿雷西博碟型天线上老化的线性馈源的底部。
One factor is that unlike the old line feed antenna, which was hanging by itself, exposed to the tropical elements, the multi-beam receiver is located inside the distinctive-looking Gregorian dome.
与老的线性反馈天线暴直接露在热带环境中不同，多通道接收器安放在富有罗马特色的穹顶中。
A sphere, in contrast, concentrates its beam to a line - which is why a "line feed" antenna was originally used at Arecibo.
球形的则不同，它会把波束汇聚到一条线上——这就是为什么阿雷西博先前使用的是“线反馈”天线。
