What type of antenna is commonly used for telemetry in falconry?

The handheld Yagi antenna is commonly used for telemetry in falconry due to its design and effectiveness in capturing signals from the transmitters attached to birds. Yagi antennas are directional antennas, meaning they can be pointed in specific directions to enhance signal strength and receive information about the bird's location more accurately. This is particularly beneficial in the field, where falconers need to track wandering birds over varying terrains and distances.

The Yagi antenna typically has multiple elements that focus on signal reception, making it highly efficient for the telemetry systems used in falconry. This allows falconers to monitor the movements and behavior of their birds, which is essential for training and ensuring the birds' safety during hunts.

In contrast, the other antenna types mentioned are less suited for this specific application. For instance, a satellite dish is designed for receiving satellite signals and is not practical for the close-range, focused tracking needed in falconry. A mobile phone antenna primarily facilitates communication services and does not have the necessary characteristics for effective telemetry. Similarly, a ground-based antenna wouldn't provide the agility and directionality required for tracking flying birds in real-time. Thus, the handheld Yagi antenna stands out as the most appropriate choice for telemetry in falconry.
