This document details the antenna performance characteristics of the Wahoo device operating in the 5GHz BT/Wi-Fi band. The testing was conducted in a free space environment using a GTEM1000 chamber, under TX-Passive conditions. The data presented includes conducted power, radiated power (peak), and antenna gain measurements across the 5150 MHz to 5850 MHz frequency range.
Key performance indicators such as dipole reference antenna radiated power, Tuna BKR810GPS connectivity, and Wahoo connectivity are analyzed. The document provides a comprehensive overview of the antenna's behavior, including a graphical representation of the antenna gain across the specified frequency band. This information is crucial for understanding the device's wireless communication capabilities and ensuring optimal performance in real-world scenarios.
The measurements were taken on February 23, 2023, with a production build verified on January 17, 2023. The PCB version used for testing was DH1. The data presented is intended to provide a detailed understanding of the antenna's performance characteristics and to support the design and optimization of the Wahoo device's wireless communication system.
