8-meter telescopic mast for remote antennas of UAVs and ground robotic systems: Stable communication beyond visual range
In modern combat, range and signal stability are the key to mission success and crew safety. The 8-meter telescopic mast is designed specifically for UAV and ground robotic system (GRS) operators who need to raise antennas or repeaters above obstacles (forest belts, buildings, terrain). This significantly expands the radio horizon and ensures stable drone control at maximum distances.
Why is an 8-meter mast the "golden mean" for the front?
The 8-meter height provides the ideal balance between long signal transmission range and unit mobility. Unlike heavy stationary structures, this mast can be deployed in minutes, which is critical when frequently changing positions.
- Maximum radio horizon: Raising the antenna by 8 meters allows you to “go around” most natural obstacles and improve the performance of FPV drones in lowlands.
- Tactical camouflage: Matte powder coating in khaki color eliminates sun glare, making the position invisible to enemy observation.
- Weather resistance: The design can withstand wind gusts of up to 20 m/sec, which allows operation even in stormy conditions.
Technical characteristics (TTX) of the 8-meter mast
The use of aircraft-grade aluminum has made it possible to achieve high strength with a weight of only 10 kg. This makes the mast easy to carry and quick to assemble by one or two fighters.
| Parameter | Value |
|---|---|
| Material | High-strength aluminum |
| Maximum height | 8 meters |
| Folded height | 180 cm (transport size) |
| Set weight | 10 kg |
| Wind load | Up to 20 m/sec |
| Coating | Powder paint (anti-glare) |
| Color | Khaki (Olive/Khaki) |
Versatility and Compatibility
The mast top is equipped with a standard 3/8 thread. This allows the installation of most modern tactical antennas, video receivers, and repeaters for Crossfire, ELRS, or digital communication systems without additional adapters.
Ready-to-Deploy Kit
We made sure that the mast is ready for use immediately after unpacking. The kit includes everything you need for secure fixation on any type of soil:
- Telescopic Mast: Main aluminum block with reliable clamps.
- 3 metal pegs: For high-quality fastening in the ground, sand or clay.
- 3 guy ropes: For stabilizing the vertical position in strong winds.
- Top 3/8: Integrated mount for an external antenna.
Applications in combat missions
- Aerial reconnaissance units: Elevating UAV control antennas for work at long distances.
- FPV kamikaze crews: Moving the repeater to a height to preserve the signal behind folds in the terrain.
- Ground robotic systems: Providing communication with mining robots or logistics platforms.
- Radio-electronic intelligence (SEAR): Raising direction finders and air scanners.
Advice from experts:Weighting just 10 kg and measuring 180 cm in length, the mast fits easily inside a pickup truck or on the back of an SUV without interfering with other equipment.
Conclusion
The 8-meter mast is a reliable and proven tool for professionals who cannot afford to lose connection. It provides the height needed to overcome obstacles while remaining lightweight and mobile.
Frequently Asked Questions about the 8-meter UAV Repeater Mast
Why is 8 meters considered the optimal height for repeaters?
This height allows the antenna to be raised above most one-story buildings and medium-sized trees, overcoming the "radio hill". According to the geometric horizon formula $d \approx 3.57 \cdot \sqrt{h}$, raising the mast by 8 meters increases the line of sight to 10 km (excluding the drone's height).
How stable is the structure in strong winds?
The 8-meter mast has moderate windage. For a stable signal without "friezes," it is recommended to use two tiers of guy lines: one at a height of 4 meters, the other closer to the top. This allows it to withstand wind gusts of up to 12-15 m/s.
What is the weight of the mast and is it easy to carry by hand?
Most models made of aircraft aluminum weigh about 6-9 kg. When folded, the length is usually 1.6-1.8 meters, which allows it to be carried in a case with a shoulder strap over significant distances.
What is the maximum payload on the top of the mast?
The design is designed for equipment weighing up to 4-5 kg. This is sufficient for simultaneous placement of a Yagi antenna, an omnidirectional dipole, and a repeater unit.
Can such a mast be installed on a moving platform (MWP)?
Yes, via a reinforced bracket. Important: during MWP movement, the mast should be folded or unfolded only partially (by 2-3 meters) so as not to shift the robot's center of gravity.
How to protect antenna connectors and cables during such a lift?
When lifting 8 meters, the weight of the cable becomes noticeable. It is recommended to secure the cable to the mast with fabric Velcro every 1.5-2 meters.This will relieve the load on the connectors and prevent damage to the cable under its own weight.
