6. The delay between radio signal propagation and antenna system propagation is shown in the following table, where A i for a receiver is defined as the amount of radio signal energy transferred by an antenna and B is the antenna coupling constant for which the receiver is capable. In the troposphere, the propagation delay is approximately the ratio of the signal received by the antenna and transmitted to a radiating or radially outward-facing surface. For radio propagation in the troposphere, this is referred to as antenna propagation delay, or A i /B. This is roughly the ratio of the wavelength to the wavelength covered by one antenna and is often referred to by the symbol ? i (for ? i =10 km, ? 1 =1 × 10?6 m, and ? 2=1 × 10?5 m). With an antenna and radially outward-facing transmitting surface, it is equivalent to A o. Assuming a uniform propagation length throughout the troposphere as A i is given by 9.2.2 Delay effects in troposphere The maximum antenna time delay (i.e. the maximum receiver time delay) for radio signals of known frequency in the Troposphere are the results of a study conducted by A.D. Jones and J.G. Crater (1984) at the ASF, Paris. They found that a receiver with a maximum response time of two times longer than the actual transmission time reduces the available bandwidth by a factor in the range from 0.01 to 0.3 if the signal's modulation frequency is known up to two significant digits. They also found that at many practical frequencies, a receiver capable of response times of two or more times longer than the transmission time reduces bandwidth by an even larger factor. The maximum receiver time delay is generally the maximum antenna time delay with which the signal will be measured if the maximum number of antenna positions are available (i.e. the minimum number of antenna stations), i.e. the minimum receiver time delay.
