List available antenna types with descriptions, typical gain, and applications.
AI agents call openems_list_antenna_types to retrieve information from Mcp Openems without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns static reference data about antenna types. It performs no modifications, executions, or destructive actions. The operation is a simple read of available antenna design options, similar to fetching documentation or a catalog.
From the tool's definition Tool name contains 'list' and description states 'List available antenna types with descriptions, typical gain, and applications' — this is purely informational retrieval with no side effects, no data modification, and no external operations triggered.
