Reasons to Choose a T-Box Antenna:

1. Larger Form Factor with Enhanced Capabilities:

▪ Space for More Features: T-Box antennas typically have a larger form factor, which can accommodate more complex and numerous internal components. This allows for greater integration of multi-band functionalities (like more MIMO configurations or additional sensors) that might not fit as easily within the compact design of a Sharkfin antenna.

▪ Higher Performance: The T-Box design may offer better performance in terms of signal strength and clarity because it can house more powerful amplifiers and larger antenna elements.

2. Rugged and Industrial Applications:

▪ Durability: T-Box antennas are often chosen for rugged environments, such as in agricultural or engineering vehicles, where the antenna might be exposed to moreextreme conditions. Their design can be more robust, making them ideal for heavyduty applications.

3. Customization and Scalability:

▪ Modularity: T-Box antennas can be easily customized and scaled to include additional communication channels or technologies. This makes them a flexible choice for vehicles requiring extensive connectivity options.

4. Installation Considerations:

▪ Surface Mounting: The T-Box design might be preferred for vehicles where a more substantial surface mount is possible or desired, offering a stable and secure installation point.

Reasons to Choose a Sharkfin Antenna:

1. Sleek and Aerodynamic Design:

▪ Aesthetics: Sharkfin antennas are favored for their sleek, low-profile design that integrates well with the vehicle’s appearance. This makes them a popular choice for passenger vehicles where design and aesthetics are important.

▪ Aerodynamics: The compact, streamlined shape of a Sharkfin antenna reduces wind resistance, making it a better choice for vehicles where aerodynamics and fuel efficiency are considerations.

2. Space Efficiency:

▪ Compactness: Sharkfin antennas are ideal for applications where space is limited, or where the antenna needs to be unobtrusive. Their compact design allows them to be installed without affecting the overall look of the vehicle.

o Roof Integration: These antennas are often integrated directly into the roof of the vehicle, which can be advantageous for maintaining a low profile and avoiding external obstructions.

3. Standard Automotive Use:

▪ Passenger Vehicles: Sharkfin antennas are commonly used in standard passenger vehicles, particularly in cars and SUVs. They provide a balanced mix of functionality and design appeal, covering essential communication needs like AM/FM, GNSS, and sometimes 5G/Wi-Fi in a compact package
