Abstract
Methods and systems for blanking a transmission signal to prevent blockage by a recurring obstruction, such as a plurality of helicopter rotor blades, are provided. An obstruction that may block a communication line of sight path is monitored. It is determined when the obstruction is expected to block transmission of a transmitted signal along the communication line of sight path based on monitoring when the obstruction blocks the communication line of sight path. A transmission blanking signal is generated, where the transmission blanking signal is configured to selectively stop transmission of the transmitted signal along the communication line of sight path when the obstruction is expected to block the communication line of sight path.
