Claim Text:
1. A method of passive condensation control of an antenna device, the method comprising: providing an antenna device, the antenna device comprising a passive condensation control system and a plurality of waveguides having an internal air volume, the passive condensation control system including regenerative type desiccant within an airflow channel that is integral with the antenna device, the airflow channel located between the internal air volume and an environment external to the antenna device; ascending the antenna device from a first altitude to a second altitude greater than the first altitude, wherein the ascending induces airflow from the internal air volume to the environment via the airflow channel, thereby releasing moisture from the regenerative type desiccant; and descending the antenna device from the second altitude to a third altitude less than the second altitude, wherein the descending induces airflow from the environment to the internal air volume via the airflow channel, thereby absorbing moisture in the regenerative type desiccant.
