Antennas
Omni-Directional Antennas
SAT offers a variety of omni-directional antennas over virtually any frequency range and polarization and can supply custom-built antennas.
Directional Antenna Systems
SAT offers a variety of directional and direction finding antennas over virtually any frequency range and can supply custom-built solutions. The accuracy of any DF system depends strongly on the local terrain, nearby metallic structures, and any buildings that would cause blockage or multi-path reception.
Adcock Antenna Array (20 MHz – 1 GHz)
Direction-Finding and Omni-directional functions from 20 MHz to 1 GHz are available with an Adcock Array. This type of DF is rapid and accurate, providing an azimuth bearing in a fraction of a second.
Two Adcock antenna array options are available, monopole (for mobile applications) on the left, and dipole (tower mounted for fixed or transportable systems) on the right.
Antenna Array (2 MHz – 3 GHz)
Omni-directional and Direction-Finding functions from 2 MHz to 3 GHz are available with a compact antenna array that can be mounted onto the surface of any land, sea or air vehicle.
Moving Dish Solutions
A general purpose directional solution for the highest frequencies is to mount a dish and antenna on a mechanical positioner. A variety of dish and positioner components can be optimized for the requirements of a specific system. The positioner may be azimuth only, or may be an azimuth and elevation positioner.
The SAT DF dish systems can receive Horizontal and Vertical linear polarizations, as well as RHCP and LHCP.
Log Periodic Antenna and Automatic Rotator
SigMon software provides for automated control of an Azimuth Antenna Rotator that can support a wide variety of directional antennas such as horizontally mounted Log Periodic antennas.
Radomes
SAT can protect any antennas or other equipment from extreme environmental conditions with an appropriately sized radome.
RF Switch Assembly
An optional RF Switch Assembly consists of a rack-mounted enclosure containing all switching modules, amplifiers, filters, splitters and combiners. A switch assembly is controlled by the site PC, and can be used to cycle through multiple antenna inputs, and/or to connect one or more instruments to an antenna. SAT can provide switch matrices of any size and complexity required.
