WL-400 QMA-Male & QMA-Female Cable Set (2x20m): Professional Tactical Extension Cable
In today's combat conditions, the survivability of a UAV operator or an electronic warfare crew directly depends on their distance from the radio source. WL-400 Coaxial Cable Set (2 pcs., 20 meters) with QMA-Male & QMA-Female connectors is a professional solution for quickly extending the length and organizing antenna extension. The use of premium Italian cable guarantees stable communication and minimal signal loss at a distance of 20 meters, allowing the operator to work from a protected shelter.
Why is the CAVEL WL-400 based extender — Is this the choice of professionals?
When extending antennas over a distance of 20 meters, every decibel of lost power can be critical. CAVEL WL 400 (Italy) cable is specially designed for Low Loss systems. It has excellent isolation from external electromagnetic interference and resistance to aggressive environments, which allows maintaining reception sensitivity and control power even when cables are connected in series.
- Minimum attenuation (Low Loss): The special dielectric structure ensures signal transmission with minimal loss at high frequencies (Wi-Fi 2.4/5.8 GHz, video links, control channels).
- Double sealing: Heat shrink on each connector is seated with a special adhesive. This guarantees 100% protection against moisture, corrosion and oxidation of contacts in the field.
- Italian quality: The marking "CAVEL WL 400 ZHN 50 Ohm LOW LOSS" confirms strict compliance with the declared characteristics at every meter.
- Resistance to the external environment: The cable sheath is resistant to ultraviolet radiation, extreme frost and moisture, maintaining flexibility even at low temperatures.

Advantages of the QMA (Quick-Lock) interface in combat
Using QMA connectors instead of classic threaded SMA or N-Type connectors gives the operator decisive advantages in critical situations:
- Speed of deployment: The Quick-Lock mechanism allows you to connect the cable in one movement, without the need to screw the threads.
- Security of fixation: The QMA-Female connector snaps tightly, eliminating accidental disconnection when pulling on the cable.
- Work with gloves: Quick-release connectors are much easier to use in bad weather or when time is short.
Expert opinion: This kit is ideal for scaling existing cable assemblies. Thanks to the high quality of the CAVEL cable, you can connect this 20-meter extender to the main cable, getting a total extension distance of up to 40-50 meters without a critical increase in SWR.
Conclusion: Reliability without compromise
The WL-400 QMA-Male - QMA-Female 20m cable kit is an investment in stable communications and personnel safety. The original Italian cable and sealed connectors make this kit the best choice for aerial reconnaissance and electronic warfare units.
FAQ: Questions and Answers for the WL-400 Extension Cable Kit (20 m,QMA MF)
1. What is the main feature of the QMA-Male and QMA-Female connectors in this kit?
The "male-female" combination turns these cables into universal extenders. You can insert them into a break in an existing line to increase the antenna extension distance by another 20 m. The Quick-lock quick-release connection allows you to connect them instantly until you hear a click.
2. Why is it important to use the WL-400 for extensions?
When increasing the length, signal losses are cumulative. WL-400 belongs to the Low Loss class, so an additional $20\,\text{meters}$ will not create critical attenuation. The system will work as efficiently as if the antenna was connected with a short cable.
3. Why are two cables included?
Modern digital systems operate in MIMO 2/2 mode (two channels simultaneously). For correct operation, both channels must be extended with identical cables. This eliminates desynchronization and guarantees a stable, interference-free picture.
4. What is the tactical advantage of extending the antenna by 20 meters?
This gives flexibility in choosing a position. If the standard cable isn't enough to reach from a bunker to a roof or tree, this kit provides an additional $20\,\text{meters}$ of safety. You remain in cover while the antenna operates at a distance.
5. How reliable is the QMA connection when extended?
QMA connectors provide a tight contact that is resistant to vibration. The Quick-lock mechanism holds the connection more securely than threaded SMA connectors. When laying on the ground, it is recommended to protect the junction of the two cables with electrical tape to prevent moisture from getting in.
6. Is the kit suitable for 2.4 GHz and 5.8 GHz frequencies?
Yes, the WL-400 is universal. At 2.4 GHz, losses are minimal, and at 5.8 GHz, they are significantly lower than those of thinner counterparts. This is an ideal solution for both control and high-quality video transmission.
