Antennas

The antennas featured on our website can be used in a variety of applications — from enhancing mobile signals to laboratory testing.
We offer both omnidirectional (Omni) and directional (LPDA) models operating across a wide frequency range: 3G, 4G, 5G, LTE, Wi‑Fi, UHF, VHF, and more. These antennas help provide stable connectivity in hard-to-reach areas, improve data transfer speeds, and enable precise measurements in laboratory conditions.

Where Can Antennas Be Used?

Antennas can be utilized in many scenarios — from improving signal reception in rural areas to professional use in testing laboratories. Below are the main use cases.

Mobile Connectivity (3G/4G/5G, LTE, Wi‑Fi)

Modern antennas such as proTAC, ZDS7, and ZHX7 work seamlessly with most mobile technologies — from classic 3G to advanced 5G. They are ideal for establishing a stable internet connection in areas with limited mobile coverage. The omnidirectional proTAC 5311 antenna delivers a reliable signal within a 35 km radius and is compatible with LTE/5G routers. Its compact and waterproof design makes it suitable for both urban environments and remote locations.

Signal Boosting in Rural Areas and Transport

In remote regions or on vehicles, signals are often weak or unstable. In such conditions, directional LPDA antennas like the COM-MW ZDS7-700-6000 — covering frequencies from 700 MHz to 6 GHz — perform exceptionally well. With up to 6 dBi gain and focused signal direction, these antennas significantly improve connectivity, even far from base stations.

Laboratory Use and Spectrum Analysis

Professionals involved in radio frequency testing, device certification, or EMC/EMI analysis require highly precise equipment. The ZHX7 series from COM-MW offers professional broadband solutions operating in the 9 kHz–200 MHz or 150 kHz–30 MHz ranges. These antennas are used with spectrum analyzers, signal generators, and antenna measurement systems.

Marine and Field Operations

Thanks to their high protection ratings (IP66/IP68), proTAC 5311 antennas withstand harsh weather, moisture, and dust. They are an excellent choice for marine vessels, military field operations, oil rigs, and energy facilities. Built-in lightning protection and temperature resistance (–40 to +85 °C) ensure stable performance in extreme conditions.

What to Consider When Choosing an Antenna

Choosing the right antenna depends on many factors, including the operating environment, frequency range, and signal type. Here are the key parameters to consider.

Frequency Range

This defines the types of connections the antenna supports. For instance, the proTAC 5311 covers 600 MHz to 6 GHz — including LTE, 5G, Wi‑Fi, and other popular standards. If you need an antenna for a specific band, pay close attention to the specifications: some models are optimized for lower frequencies, others for higher ones (like Wi‑Fi or 5G NR).

Antenna Type: Omni or Directional

Omni antennas provide 360-degree coverage, making them ideal for mobile communication in urban or mobile environments. Directional (LPDA) antennas focus the signal in a specific direction, providing stronger gain but requiring precise alignment.

Gain

Gain indicates how much the antenna can amplify signal reception or transmission. For example, the ZDS7-700-6000 offers a 6 dBi gain — improving connection quality over long distances.

Radiation Efficiency and VSWR

Higher antenna efficiency means less energy loss during transmission. The proTAC 5311 features up to 100% radiation efficiency and a low VSWR (< 2.0), indicating high performance with minimal signal loss.

Durability and Environmental Resistance

For outdoor or marine use, antennas must be protected against moisture, dust, lightning, and temperature extremes. proTAC models meet the IP68 standard, while ZDS7 models comply with IP66 — ensuring durability and reliable operation in the harshest conditions.

Mounting and Connectors

The antenna should be easy to install and compatible with your equipment. For example, the proTAC 5311 comes with a mounting flange and an N-Female connector. The ZDS7 features an SMA connector and includes a mounting kit for vehicles or masts.
