Effect of Distance and Antenna Height on Fading In planning this work a survey for a receiving site was made bymeans of a portable receiver in a car. Later, simultaneous reception ULTRA-SHORT-WAVE TRANSMISSION 505 was had at East Moriches and West Sayville, on three days. Thesurvey data were not sufficient to establish any proposition beyondthe statement that the signal strength fell rapidly with distance, withthe intensity of fading coming up as the signal fell. The simultaneoustwo-distance recording showed random fading between the tworecords with less fading amplitude at the shorter distance. Thefading rate was about the same. Unfortunately the recording tookplace under scintillation conditions, thus giving very poor records forcomparison purposes. By mounting
