Is an STC required to install an HF system?
While you can use an STC to install an HF system, it is not required. An HF system can be installed as a follow-on field approval. FAA order 8300.10 provides guidance for a follow on field approval by the FAA. In most cases a DER can approve the electrical and structural installation.
