I know the first one. The narrowest part of the antenna points to a major city where the TV transmitter is located. The left and right triangles have to do with your receiver being operational or not as I recall. I think right turns is with an operative receiver. Without a transponder which would make this an easy fix I doubt if any controller would notice you before you ran out of gas. Now with analog TV being gone the little digital antennas aren't being used much so at least you could see where south was using the Directv antennas depending on what region you were in. Remember flying the old 727 types with no magenta line? Entering holding was fun then. You couldn't just push a button. Now getting an instrument rating probably only requires a 10 hr typing course. That will probably be standard in 2020.
