DIRECTIONAL VS OMNI

Why Choose Directional Data Links?

“Both Iraq and Afghanistan produced examples of an environment where nearly anything that was turned on interfered with something else.” ¹ Troll Systems microwave antennas utilize tracking systems and directional, narrow beamwidths to achieve the greatest possible efficiency and performance.

Due to the increase in demand for spectrum, many areas of the world are saturated in radio frequency transmissions which is causing widespread interference. 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 and increasing potential congestion in the available spectrum.

Troll Systems’ airborne and ground spectrum high-gain tracking antennas and radio frequency ground stations are designed to manage spectrum efficiently. Furthermore, the technologies we implement are already 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.
