(42S) RMS - Antenna gain decrease due to roughness of the reflector surface

[Emilio Abud Filho]

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.

Attachments:

- Program documentation, including example, math equations, how to use explanations, source code, etc; (xlsx and pdf)

- RAW format file (zip)
