Choosing the Right Antenna
Choosing the precise antenna is crucial in optimizing the performance of your network. Each antenna has its place in the telecommunication infrastructure. Ranging from low-profile mobile antennas for fleet management and smart expressway systems, or omnidirectional base station antennas for cellular networks, each antenna has different functions within each network ecosystem.
As telecommunication RF antenna manufacturers, we carefully consider various parameters to ensure maximum performance across all our antenna products. We aim to maximize the performance of our products across all use cases, allowing us to deliver maximum customer satisfaction.
There are several key considerations when choosing an antenna for your application:
It is important to take note of the frequencies supported by your antenna. An antenna’s bandwidth and frequency range are connected, with the latter representing the range of frequencies over which it meets a particular parameter specification. We supply a wide portfolio of antennas which cover a wide range of frequencies. Our UHF TV antennas, for instance, are engineered to support spectrum in the 470MHz and 698MHz range while our cellular antennas are compatible with many global 3G and 4G frequency bands.
The Voltage Standing Wave Ratio:
VSWR measures the mismatch between an antenna and its feed line and generally represents how efficient RF power is transmitted from a power source through a transmission line. While, ideally, a 100% energy transmission is desired, a 2:1 VSWR is a commonly used VSWR specification. Antennas that are not correctly matched may not radiate power.
Gain is related to antenna directivity. Directivity measures an antenna’s capacity to focus radiation rather than spread it evenly across a wide-angle range. Gain is measured in decibels (dBi), and generally, the higher the gain, the more capable the antenna is able to radiate frequencies.
Line-of-sight, height & distance between antennas, and the earth’s curvature must all be considered while placing antennas. While omnidirectional antennas receive and send signals in a 360º radius, yagi antennas are directional, and must be set up differently. Due to the limited line-of-sight range of VHF broadcasts, antennas should generally be set high. Inside antennas should also be placed differently depending on type.
An omnidirectional antenna radiates and receives energy equally in all horizontal directions. An antenna can also focus energy in a particular direction, making it directional. For some applications, all-around coverage is either unnecessary or desirable.
Antennas can make or break your network
Selecting an antenna is a critical step in the design of your network.
