Antennas

Commercial antennas are an essential component in many communication systems. They are designed and manufactured to meet high standards of performance and quality, serving a variety of frequencies and purposes, including UHF (Ultra High Frequency), HF (High Frequency), LTE (Long Term Evolution), and GSM (Global System for Mobile Communications).
Designing a commercial antenna typically involves careful consideration of the required performance parameters, including frequency, power handling, bandwidth, and the physical constraints of the installation. Commercial antennas are designed to transmit and receive signals effectively and efficiently, often within challenging environments.
When choosing a commercial antenna, it's important to consider the specific requirements of the communication system it will be used in. For example, an antenna for a GSM system may have different requirements compared to an antenna for a UHF system. Therefore, it's important to check the specifications of the antenna to ensure it is suitable for the intended application.

More Information about Commercial Antennas
Yagi antennas
Yagi antennas radiate and receive radio frequency (RF) energy equally in all horizontal directions. This broad coverage area increases the probability of maintaining connection stability, however the potential for interference and lower throughput is more likely.
Omni antennas
Omni antennas radiate and receive RF energy in a selected direction, usually around 45 to 90 degrees. The signal from the target area is improved through directivity gain as long as there is no congestion. Interference is held to a minimum.
Whip antennas
Whip antennas are the most common type of monopole antenna. They are a flexible, straight rod designed to pick up different frequency waves depending on the length. The bottom of the antenna is connected to the transmitter or radio receiver and is great for picking up the higher frequencies of HF, UHF and VHF radio bands.
Cellular antennas
Cellular antennas cover the entire spectrum of cellular standards including UMTS, GSM and LTE, with speeds from 2G to 5G. A mobile cellular antenna is perfect for applications that need a compact communications solution, such as public transit, automobiles, or remote sites and other industrial applications. Lightweight and customizable, these antennas can be selected by their mounting and connection types.
Connection
Many of these antennas are connected to a transmission line, which carries the signal from the antenna to the receiver, or from the transmitter to the antenna. The type of transmission line used will depend on the specific requirements of the system.
There are a vast number of commercial antennas available on the market, each with their specific designs, features, and capabilities. These can be ordered directly from the manufacturing company or through distributors. Furthermore, commercial antennas must be constructed with high-quality materials to ensure longevity and reliable performance. Therefore, it's essential to order antennas from reputable manufacturers.
FAQs
How many companies manufacture and design commercial antennas?
It is safe to say there are hundreds of companies that manufacture commercial antennas and they span numerous different markets and applications, from telecommunication, broadcasting, and satellite communication, to industrial, scientific, and medical applications.
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.
