For tracking Low Earth Orbit (LEO) satellites, the best antenna type is typically the Yagi-Uda antenna. This choice is due to several reasons:

1. Directional Gain: Yagi antennas offer high directional gain, which enhances the signal reception from satellites moving across the sky. This gain is crucial for tracking fast-moving LEO satellites that traverse a large portion of the sky.
2. Beamwidth: The narrow beamwidth of a Yagi antenna allows it to focus on a specific satellite, improving signal strength and reducing interference from other sources.
3. Cost-Effectiveness: Yagi antennas are relatively inexpensive compared to other high-gain antennas, such as parabolic dishes, making them a practical choice for amateur and semi-professional tracking setups.
4. Ease of Use: They are straightforward to set up and align, which is beneficial for users who need to track satellites manually or semi-automatically.
5. Compact Size: Yagi antennas are more compact than parabolic dishes, making them suitable for installations in limited spaces.

Overall, the Yagi-Uda antenna balances performance, cost, and ease of use, making it ideal for LEO satellite tracking.
