Why Choose Directional Data Links?

As the demand for Radio Frequency (RF) spectrum grows, many areas of the world are already saturated with RF transmitters that cause widespread interference with one another.  In the future, the assignment of radio frequency spectrum may require a system that prioritizes national, international and global allocation or distribution that limit the available microwave frequencies creating an increasing potential for congestion in the available spectrum. 

Troll Systems’ airborne and ground high-gain tracking antennas and radio frequency ground stations are designed to manage spectrum efficiently. The technologies we deploy are well suited to a future where spectrum management is likely to be required for military, civil and commercial interests.

1. Narrow Directional Bandwidths

  • Are resistant to interference and jamming
  • Require less power to transmit to the radio horizon.
  • Improve spectrum management in crowded RF environments, leading to better frequency availability.

2. Antenna Signal Radiation Patterns Directional vs. Omni

  • Omni antennas radiate RF energy in every direction, making frequency availability and / or reallocation difficult in concentrated RF environments.
  • Omni antenna radiation patterns are easy to locate, jam and interfere with in operational environments.   
  • To increase range, omni antennas generally require more power leading to more heat, weight and spectrum inefficiency.
