Scala Antennas
The antennas made by Scala are high-performance communication devices designed for the kinds of industry and professional applications where reliability, ample ruggedness, and precision are non-negotiable. They are known for those attributes and also for superior engineering in "tough but smart" antenna designs that get the job done across a lot of applications in a number of industries.
Scala has broadcast antennas and antenna systems that serve in industrial applications where wireless communication is a must—reliably, efficiently, and effectively. The strong mechanical build guarantees a lengthy operational lifetime, even in extreme environments like marine, desert, or mountaintop conditions. This makes them suitable for both stationary and mobile applications.
FAQs
What frequency range does the SCALA TY-900 cover?
The SCALA TY-900 is designed for the 890-960 MHz range (professional fixed station applications). It offers broadband support in that region which is suitable for many communications and industrial telemetry uses.
What gain and power handling does the SCALA TY-900 have?
The TY-900 example features around 12.15 dBi gain (for the 7-element version) and a power input rating of ~100 Watts in the spec listing I found. That gives you a sense of its capability for fixed-station links.
What is SCALA TY-900's construction-quality and suitability for harsh environments?
These SCALA antennas are built with heavy-duty materials: anodized aluminum, robust castings and stainless steel hardware. They are designed for “severe environmental conditions,” excellent for industrial, outdoor mountings.
Is the SCALA TY-900's polarization fixed or can it be selected?
In many SCALA Yagi models the polarization can be horizontal or vertical (depending on the mounting) really giving flexibility for matching your site requirements and aligning with the rest of the communications system.
How important is impedance matching and VSWR for SCALA TY-900 antennas?
Very important. For example one SCALA Yagi spec shows VSWR < 1.35:1 in its band. Proper feedline, correct connector, and mounting height all matter to ensure efficient transmission and minimal reflections, especially in control/telemetry systems.
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.
