(42S) RMS - Antenna gain decrease due to roughness of the reflector surface - Emilio Abud Filho - 11-05-2022 01:17 PM
Dear All
Program for solving the antenna gain decrease value due to deviation of the reflector surface from its required shape (roughness RMS), as a function of operating frequency; to be used with "HP Solver" built-in application.
