Freewave Antennas

FreeWave antennas are tailored for long-range, industrial-strength wireless communication, making them a preferred choice across many sectors. The company was an early pioneer in the IIoT space and now offers several antennas capable of being part of a wireless network run by FreeWave equipment.
These antennas cover a variety of types—whip, coil, directional, and omni-directional—as well as complete kits with mounts and cables for just about any application. Some schematics accompanying the description of the antennas show them capable of being installed in a horizontally polarized position—a setup that might be required for certain signal-path configurations. The whip antennas employ a long, slim form factor and are suitable for applications where an omnidirectional setup close to the antenna is necessary.
The directional antennas offer high gain and good front-to-back ratio performance that make them useful for establishing line-of-sight communication—that is, communication in a straight line from one antenna to another, as opposed to around in a circle, inside a sphere, or through a series of reflectors. FreeWave antennas are vitally important to the operation of industrial communication networks. They enable uninterrupted data flow between the individual parts of a system, which is crucial for "edge" automation; that is, for smart systems in remote, hard-to-reach places.
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.
