Collinear Antennas

What are collinear antennas?

A collinear antenna is a vertical antenna assembled from several identical sections that work as a single system. This design forms the signal along the horizon, not upwards, making long-distance communication more stable. This is noticeable in operation: under the same conditions, a collinear antenna maintains the signal longer and provides more even coverage than shorter options. Antennas are often selected simultaneously with the purchase of EW systems.

What are collinear antennas used for?

Collinear antennas are used where stable long-distance communication is critical. These include base stations, two-way radio operation, or communication with UAVs and drones, where the signal must remain predictable despite changes in position or distance. At 144 MHz and 433 MHz, such antennas provide more uniform coverage and allow operation without sharp signal losses.

Collinear Antenna Characteristics

When choosing collinear antennas, the following parameters are usually considered:

• frequencies — a collinear antenna must match the equipment's range;
• gain — determines how far communication is maintained;
• length — affects installation and height;
• cable — signal loss depends on it;
• design — the rigidity of elements affects operational stability.

Recommendations for Choosing Collinear Antennas

In open terrain, longer antennas for EW yield better results due to greater range. In environments with obstacles, such as urban areas or wooded terrain, shorter options that are easier to position correctly sometimes work more effectively. Installation height directly affects communication quality, so the antenna should be raised above the level of obstacles. Selection should consider frequencies and operating conditions to avoid replacement after initial use.

Where to Buy Collinear Antennas?

When choosing collinear antennas, which can be purchased at Flash Army, you should focus on frequencies and usage conditions. In the catalog, you can find not only collinear antennas but also buy antennas for a specific task, along with cables and compatible elements, so that the system works without additional selection after installation. 

On the website, you can also find other military equipment and outdoor recreation items. Our consultants are always happy to help with selection based on your needs, and fast delivery across Ukraine is a lifesaver when items are needed urgently.
