First, depositional turbidity currents are imposed on steep slopes in both flume experiments and numerical cases, exclusively based on a configuration consisting of an upstream sloping portion and a downstream horizontal portion linked by a slope break. This appears physically counterintuitive as steep slope should favour self-accelerating erosional turbidity currents (Parker et al. 1986) Radio Antenna Engineering read for free In recent times, the cost of airtime over L-band and VSAT communications has dropped significantly, giving ship owners more choice and flexibility (depending on the type of vessel and level of IT integration).

In some receiving applications, the very inefficient antennas may have little impact on performance. At low frequencies, for example, atmospheric or man-made noise can mask antenna inefficiency. For example, CCIR Rep. 258-3 indicates man-made noise in a residential setting at 40 MHz is about 28 dB above the thermal noise floor. Consequently, an antenna with a 20 dB loss (due to inefficiency) would have little impact on system noise performance System Issues for Adaptive Antennas in Umts (Development of adaptive basestation antenna systems for use with current & future mobile communications systems - part 2) The transition to data has forced satellite communication operators to become solution providers.
