DMS Omni Antennas
DMS Omni antennas provide robust, high-performance wireless communications across a wide variety of industrial, commercial, and outdoor applications. They are typically designed and engineered to deliver reliable omnidirectional coverage in a full 360-degree horizontal plane, which makes them suitable for all sorts of systems that need connectivity from all directions: SCADA, for instance, or IoT networks.
Because most DMS models are built for an all-indoor, all-outdoor ruggedness that encompasses anything from industrial sites to places where antennas are likely to be exposed to all kinds of environments. Depending on the model and application, the gain levels generally fall between 2 and 9 dBi. This ensures a nice balance between how far the signal travels and how strong the signal is when it gets there, between from point to multipoint—where the receiver could be at any angle—or for systems on the move.
Antennas: Omni vs Yagi
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.
Advantages and Disadvantages
• Easy setup and install
• Can send and receive signals from multiple locations with just one antenna
• Limited on the distance it can communicate
• Not a great option from areas with poor signal strength
