GMDSS for establishing Sea Area Al for GMDSS VHF 156 174 MHz Sea Area Al is that area which is within a circle of radius A nautical miles over which the radio propagation path lies substantially over water The radius A is equal to the transmission distance between a ship s VHF antenna at a height h of 4 metres above sea level and the height H of the antenna of the VHF coast station which lies at the centre of the circle The following formula should be used to calculate the range A in nautical miles A 2 5 Square root of H in metres Square root of h in metres H is the height of the coast station VHF receiving antenna and h is the height of the ship s transmitting antenna which is assumed to be 4 metres By default if not manually declared the interference area will be assumed to be a circle with radius 120nautical miles This is the range in cnn icon AE YNE i or which FATDMA reservations have to be EY CIDE SSO Ok respected by mobiles if received over gt abnormal distances during periods of extended propagation PLEASE NOTE that if you modify the antenna height parameters your coverage declarations ae not changed You may manually reset the coverage to the default circle or polygon resembling the default coverage range by right clicking on one of your stations and selecting reset to circle or reset to polygon but this requires that the relevant layer receive transmit or interference
