Antenna Design

OMNI vs DIRECTIONAL ANTENNAS

Omni Antennas radiate the signal in all directions equally, making frequency availability and / or reallocation difficult in concentrated RF environments. To increase range, omni antennas generally require more power leading to more heat, weight and spectrum inefficiency.

Troll Systems' microwave antennas transmit in narrow beam widths and direct their RF energy precisely at ground receive sites.  This enables Troll's data link solutions to achieve the greatest possible throughput, range and efficiency.
