Collinear Antenna 830-890 MHz (6 dBi): High-Precision Gain for Electronic Warfare and Communications
In today's electronic warfare environment, control of the frequency spectrum determines unit survivability. Collinear Antenna 830-890 MHz is a highly specialized solution designed to operate in one of the most active UAV control and telemetry bands. With a high gain of 6 dBi and a collinear structure, this antenna delivers maximum signal density exactly where it's needed to effectively suppress enemy threats or ensure stable tactical communications.
The strategic advantage of the 830-890 MHz band
The 830-890 MHz band is critical for digital command and control channels. Using an antenna with a precisely tuned frequency window allows for perfect matching with the transmitter, which is critical for preserving the service life of expensive electronic warfare modules. Key advantages of this model:
- Power concentration: A narrow vertical beamwidth (17º) focuses radiation along the horizon, significantly increasing the range compared to standard wideband solutions.
- Loss minimization: SWR ≤ 2.0 ensures efficient power transfer from the amplifier to the antenna, preventing equipment overheating.
- 360° coverage: Provides complete protection of an object or equipment in the horizontal plane, leaving no vulnerable sectors for drone attack.
Technical and tactical characteristics (TTX)
This antenna is optimized for operation with powerful digital jamming modules (VCO) and tactical communication repeaters.
| Parameter | Characteristic Value |
|---|---|
| Operating Frequency Range | 830 - 890 MHz |
| Gain | 6 ±1 dBi |
| SWR | ≤ 2,0 |
| Polarization | Vertical |
| Horizontal Beamwidth | 360º (Omnidirectional) |
| Vertical Beamwidth | 17 ± 3º (focus on horizon) |

Combat applications:
The high power handling of 70 W makes this antenna an ideal choice for active electronic countermeasure systems.
- Automotive electronic warfare systems: Installation on the roof of pickup trucks and armored vehicles to create a protective dome from FPV kamikazes in the 800+ MHz range.
- Trench protection: Use in positions as a remote element to suppress telemetry channels of reconnaissance UAVs.
- Tactical repeaters: Increasing the range and stability of communication between units on the corresponding frequencies.
Expert assessment: The collinear design is the "gold standard" for ground use. It eliminates the need to waste transmitter power on useless radiation "into the sky," directing the entire resource parallel to the ground, which is critical for engaging low-flying targets.
Reliability and survivability
The antenna is made of high-quality materials resistant to vibration, precipitation, and significant temperature changes (from -40°C to +70°C). The N-Male connector ensures a reliable, sealed connection and minimal signal attenuation, which is especially important in intense combat conditions.
Conclusion: Maximum efficiency of your equipment
Collinear antenna 830-890 MHz (6 dBi) is an investment in survivability and efficiency. It allows your EW module or radio to operate at its maximum capabilities, providing the necessary advantage in the radio airwaves.
Tactical FAQ:Six Questions About the 868 MHz Collinear Antenna
Why is the 830-890 MHz band considered "surgical precision"?
This antenna is most effective at 868 MHz — the ExpressLRS (ELRS) protocol. It concentrates all the module's power in this corridor, where the FPV kamikaze control signal goes, providing maximum suppression efficiency.
What does 5 dBi gain give to the protective dome shape?
5 dBi creates a "flat donut" of interference. The signal goes further along the horizon than with a conventional antenna, but still maintains density overhead. This prevents the drone from slipping through the "blind spot" during a vertical attack or steep dive.
What is the advantage of a collinear design over a conventional one?
A collinear antenna is a stack of emitters. It works like a studio softbox in photography: with the same source power, the light (interference) is directed much more effectively at the target, which increases the "jamming" range without overheating the module.
Impact on Starlink, laptop, and mobile communications?
Electronic warfare in this range is safe for Starlink and Wi-Fi. You can study notes or play Bannerlord under the protection of the dome. However, mobile Internet and GSM-900 communication near the antenna may work intermittently.
Correct installation on the roof of the car?
The antenna must be located exactly in the center of the roof. The metal surface of the car serves as a reflector (ground plane). Shifting the antenna to the edge distorts the protected zone, leaving "gaps" that can be exploited by the enemy.
The main danger during operation?
Frequency mismatch. If you connect this antenna to a module of a different range, a high SWR will occur. Energy will return to the device, and the module will burn out instantly. Always check the frequency markings before turning on the power.
What does 5 dBi gain give to the shape of the protective dome?
5 dBi creates a "flat donut" of interference. The signal goes further along the horizon than with a regular antenna, but maintains density overhead. This prevents the drone from slipping through the "blind zone" during a vertical attack or steep dive.
