SLL-400 N-Type Cable (20m): Professional Tactical Extension Cable with Low Attenuation
In today's high-tech warfare, the position of a UAV operator or an EW crew is a priority target for enemy electronic intelligence (SIGINT). The 20-meter SLL-400 coaxial cable with N-type & mdash; N-type connectors allows for effective remote extension of antennas. This is critical for personnel safety: antennas are placed on masts or elevated surfaces, while the operator remains in a protected shelter (dugout or basement) at a safe distance from the radiation source.
Why SLL-400 & mdash; The best choice for tactical missions?
At a distance of 20 meters, the quality of the conductor determines whether the signal will reach the antenna or "die out" in the cable. SLL-400 is a Low Loss cable and is a modern alternative to LMR-400, offering improved performance for harsh frontline conditions.
- Minimum attenuation (Low Loss): The special dielectric structure ensures the passage of high-frequency signals with minimal decibel power loss.
- Increased flexibility: Unlike the rigid LMR-400, SLL-400 cable is much easier to deploy in trenches, dugouts, or when laying through dense vegetation.
- All-weather reliability: The outer jacket is resistant to ultraviolet radiation and moisture, which allows the cable to be used both indoors and in extreme outdoor conditions.
- Perfect matching 50 Ohm: Full compliance with military communication standards eliminates the risk of equipment overheating due to high SWR.

Advantages of N-Type connectors in detail
The cable assembly is equipped with industrial N-type connectors, which are the standard in military and professional electronics:
- Mechanical strength: The threaded connection guarantees complete tightness and reliable fixation, resistant to strong vibrations and shocks.
- Low SWR: High-quality connectors provide minimal signal reflection, protecting your transmitter (booster) from failure.
- Wide range: Stable operation on frequencies used for UAV control and video transmission (900 MHz, 1.3 GHz, 2.4 GHz, 5.8 GHz).
Expert opinion: Using a 20-meter extension based on the SLL-400 allows the operator to be in deep cover, while significantly improving the line of sight horizon for antennas installed at a height. Due to low attenuation, you do not lose reception sensitivity, which directly affects the range and success of the combat mission.
Areas of tactical application:
- FPV units: Connecting remote antennas to ground control stations.
- Electronic warfare / SIGINT systems: Removal of suppression or detection antennas from personnel to reduce the risk of direction finding.
- Communication services: Laying lines to repeaters and powerful signal amplifiers (boosters).
Conclusion:Reliability without compromise
The SLL-400 N-Type 20m cable is professional equipment for those who value communication quality and unit safety. Its flexibility, low attenuation, and resistance to external factors make it the best tool for aerial reconnaissance and electronic warfare units.
FAQ: Six questions about the SLL-400 cable (20 m, N-type)
What does the abbreviation SLL in the cable name mean?
SLL stands for Super Low Loss. This is a premium cable designed to transmit signals with minimal attenuation, even at high frequencies (e.g., 5.8 GHz). It preserves the maximum power of your remote control compared to standard cables.
Why is 20 meters the "golden mean"?
The 20 meters length is the perfect balance: the operator is in a safe shelter away from the antenna, and signal loss in the cable remains minimal, allowing the system to work efficiently.
Are N-type connectors reliable in the field?
N-type connectors are sealed and equipped with massive threads. They are not afraid of rain, snow, and dirt. Moisture will not get inside the connection, which eliminates corrosion and sudden signal loss during a mission.
Is the cable suitable for 2.4 GHz and 5.8 GHz frequencies?
Yes, the SLL-400 is specially optimized for operation in these ranges. It delivers the video signal and control commands without the picture "scattering", which often happens when using cheap cables at such lengths.
What is the physical durability of the cable?
The cable has a durable sheath that is resistant to sun and frost. Its thickness (10 mm) protects it from accidental damage. The main thing is Avoid sharp bends (at least 10 cm radius) to maintain the integrity of the internal insulation.
Compatibility with amplifiers (boosters)?
The SLL-400 is ideal for connecting professional boosters (Alientech, AvengeAngel). This is a reliable line that guarantees a stable connection without dropouts.
Low attenuation and resistance to external factors make it the best tool for aerial reconnaissance and electronic warfare units.
