(42) SQUINT - Antenna main beam deviation for CP offset parabolic antenna

[Emilio Abud Filho]

Dear All

Program for solving the main beam deviation angle (Squint) for circularly polarized (CP), offset reflector antennas, based on the antenna diameter, focus/diameter ratio, feeder offset angle and 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)
