The average person can notice the effects of changes in radio propagation in several ways. In AM broadcasting, the dramatic ionospheric changes that occur overnight in the mediumwave band drive a unique broadcast license scheme in the United States, with entirely different transmitter power output levels and directional antenna patterns to cope with skywave propagation at night. Very few stations are allowed to run without modifications during dark hours, typically o… Webcenter of the drawing. From Point A the signal travels via the ionosphere again to Point B, at the right.

Web21 jan. 2015 · For 900 MHz at 20 miles (32 km), you would need antennas of at least 46 m (152 ft) to achieve a good signal. In many practical settings, your transceivers may function with a lower antenna height, but the higher the better. There is also a trade-off between the antenna height and the amount of RF cable needed to span the transceiver to the antenna. WebAnswer (1 of 4): FM is a type of modulation, which has not relationship to the distance a signal with travel.
