Antennas For Point-to-point Radio Services
In most applications line-of-sight is required between the transmitting and receiving antennas for point-to-point services, and antennas may have to be mounted at a certain height about ground. For microwave radio systems, it is not always possible to use long transmission lines between transmitter and antenna, so towers with equipment rooms or cabinets close to the height of the antenna may be required.

Famous quotes containing the words radio and/or services:
“The radio ... goes on early in the morning and is listened to at all hours of the day, until nine, ten and often eleven o’clock in the evening. This is certainly a sign that the grown-ups have infinite patience, but it also means that the power of absorption of their brains is pretty limited, with exceptions, of course—I don’t want to hurt anyone’s feelings. One or two news bulletins would be ample per day! But the old geese, well—I’ve said my piece!”
—Anne Frank (1929–1945)
“Working women today are trying to achieve in the work world what men have achieved all along—but men have always had the help of a woman at home who took care of all the other details of living! Today the working woman is also that woman at home, and without support services in the workplace and a respect for the work women do within and outside the home, the attempt to do both is taking its toll—on women, on men, and on our children.”
—Jeanne Elium (20th century)
