ALT Ticker-tape parade for presidential candidate Richard Nixon in New York in 1960.
ALT Three excellent humans holding a subreflector. That's the part that goes on the long arm of the satellite dish, to reflect the reflection from the main dish back, so that you can mechanically fit a feed in a moderately-sized dome. If you're not into satellite dishes: Holler, from a distance, into a big parabolic salad bowl. There will be a point in front of the bowl where the sound gets focused and loud, perfect for a sensitive microphone to be put. Now, small problem: You're floating above the slanted salad dish, and putting that microphone somewhere between you and the dish requires a very large tower. Instead, you mount a second, smaller, sub-salad-dish somewhere between that focal point and the large bowl, facing back to the bowl: you will have a focal point somewhere between salad-bowl and sub-salad-bowl, which makes the whole system smaller. Now, this salad bowl is 13 m in diameter, 1960s NATO weight, and the sub-salad-bowl is still about 1.5 m in diameter. It's heavy.
