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. WebRadio propagation is the behavior of radio waves as they travel, or are propagated, from one point to another in vacuum, or into various parts of the atmosphere.
