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 utilize tracking systems and directional, narrow RF spectrum to achieve the greatest possible efficiency in transmission and reception. Troll's directional antennas transmit in narrow, 30 degree cone-shaped patterns directed at the ground sites.
