Executing Class Two Permissive Changes for Substituted Host Antennas
Substituted host antennas qualify for Class II Permissive Changes only when peak gain stays below certified limits and radiative physical structure remains identical.
Form 731 Application
Meaning
The mandatory administrative filing required by the Federal Communications Commission to obtain an equipment authorization grant for an intentional radiator. Submitting a completed form 731 application represents the final stage of the device certification process in the United States. This document collects administrative details about the applicant alongside the technical specifications of the wireless hardware.
Submission Sequence
The certification process begins with the generation of a unique grantee code and the completion of laboratory testing. Once the testing laboratory compiles the necessary reports, the applicant uploads these files alongside the form 731 application to a telecommunication certification body. Reviewers at the certification body then check the files for conformity and submit the final approval to the federal database.
This step prevents unapproved hardware from entering the commercial market.
Administrative Record
The filed document acts as the public registry of the certified equipment’s frequency bands, power ratings, and emission designators. Future design modifications refer back to this form 731 application to determine if the changes require a new certification or a permissive change. It remains a permanent, searchable entry in the official database.
Technical Appendix
The package includes schematic diagrams, block diagrams, and operational descriptions of the wireless module. This detailed documentation supports the assertions made in the form 731 application, allowing reviewers to verify the layout of the RF circuitry.
