DC–8GHz LMR240 QMA RF Cable for Antennas and Signal Amplifiers ACASOM | Chipomi

The ACASOM LMR240 soft RF coaxial cable is built for projects where stable signal transmission, flexible routing, and low insertion loss matter. Its soft-type construction makes it easier to coil, install, and manage than stiffer cable assemblies, which is especially useful in mobile, outdoor, and space-constrained RF setups. According to the supplier specification, this cable is designed with 50 Ohm impedance and supports a DC–8GHz operating range.

This cable assembly is intended for extending the connection between antennas, signal amplifiers, and other compatible RF components. The straight QMA male to QMA female connector configuration makes it suitable for matching extension paths where secure, practical integration is required. The supplier also highlights low loss, high temperature resistance, and high-frequency capability as core product features.

Each cable assembly is stated to be 100% tested for continuity and rated for dielectric withstanding voltage up to 1500 Vrms. The same supplier specification lists a maximum frequency of 8.0GHz, a maximum voltage of 500V, and an operating temperature range from -40℃ to +85℃, making this a solid option for demanding RF infrastructure and field deployment scenarios.

FAQ:

1. What is this cable mainly used for?
   It is designed for extending connections between antennas, signal amplifiers, and other compatible RF components where flexible low-loss cable is needed.
2. What connector type is used in this version?
   This specification lists a straight QMA male connector on one end and a straight QMA female connector on the other end.
3. What impedance does the cable have?
   The cable is specified as 50 Ohm, which is standard for many RF systems.
4. What frequency range does it support?
   The supplier lists the operating range as DC–8GHz.
5. How should I choose the cable length?
   Choose the shortest practical length for your installation while checking the published insertion loss values for 2.4GHz and 5.8GHz. Longer runs introduce higher loss.
6. Is it suitable for outdoor use?
   The supplier description positions it for demanding outdoor environments and mobile RF applications.
7. Which length options are most relevant for this product listing?
   The supplier page presents this item with 10m, 15m, and 20m selectable variants.

The ACASOM LMR240 soft RF coaxial cable is a practical choice for buyers who need reliable signal extension between antennas, signal amplifiers, and other RF components without moving to bulky or hard-to-route cable assemblies. On Chipomi, this model is especially relevant for users looking for a flexible low-loss cable that can be used in antenna lines, amplifier extensions, mobile installations, and outdoor RF projects. With a specified operating range of DC–8GHz and 50 Ohm impedance, it fits a broad set of compatible wireless and signal extension applications.

One of the strongest advantages of this cable is its soft LMR240 construction. Compared with stiffer coax options, it is easier to route through installation paths, easier to coil for storage, and easier to use in field deployment scenarios. The straight QMA male to QMA female connector layout also makes it practical for compatible extension tasks where secure, straightforward connection matters. The supplier further states that each cable assembly is 100% tested for continuity and rated for dielectric withstanding voltage up to 1500 Vrms, which adds confidence for users who need dependable RF hardware.

Another major benefit is the published signal loss table. Buyers can compare insertion loss at both 2.4GHz and 5.8GHz before choosing cable length. For example, a 10 Meter cable is listed at 4.3dB loss at 2.4GHz and 6.7dB at 5.8GHz, while a 20 Meter cable reaches 8.6dB and 13.4dB respectively. This makes the product easier to select for real projects because you can balance routing distance against expected RF loss instead of guessing.

If you need an ACASOM RF coaxial cable for antenna systems, signal amplifier connections, drone-related RF setups, or general wireless infrastructure, this LMR240 soft cable gives you a strong balance of flexibility, compatibility, and defined performance. Order from Chipomi if you want a practical RF cable option available in 10m, 15m, and 20m lengths for clean installation and more predictable signal planning.
