DMS Antennas
DMS antennas are built for toughness and signal integrity, and they are an excellent choice for the industrial and commercial applications where data needs to be transmitted wirelessly. They are used in machine-to-machine communication, telemetry, fleet management, and other monitoring applications that are just as likely to be outdoors as in a factory or office.
The DMS product line includes antennas that work with various wireless technologies. Some of them are omnidirectional, meaning that they can receive signals well even if the source is located anywhere around them 360 degrees in the horizontal plane. Other models are designed to be very directional, that is, for receiving signals from a source that is more or less in line with the direction that the receiving antenna is pointing.
Antennas: Omni vs Yagi
Yagi Antennas
Yagi Antennas are directional antennas that can transmit and receive data coming from a specific direction (the direction the antenna is facing). Thus, directional antennas must be aimed in the direction of the potential signal transmitter. Aiming the antenna correctly is essential for optimal reception. Knowing the width of the antenna's signal pattern is the best way to ensure optimal aim.
Omni Antennas
Omni Antennas can pick-up signals coming from all directions. They are most commonly used for signal reception over a large area where the potential location of any incoming signal's transmitter varies. Therefore, unlike Yagi antennas, Omni antennas do not need to be pointed in a particular direction. Each specific antenna has a gain rating or dBi (decibel isotropic) number which coincides with the performance of the antenna. The higher the dBi rating, the larger area covered.
