XRDS -RF 40FT SMA Male to SMA Female Low-Loss Cable

XRDS -RF 40FT SMA Male to SMA Female extension cable is a low-loss, 50 Ohm KMR240 coax designed to extend SMA antenna connections with durable, weather-resistant construction.

If you need to move an antenna or radio device farther from its original port without sacrificing signal integrity, this 40-foot SMA male to SMA female cable provides a reliable connection. Built around KMR240 low-loss coax and a solid copper core, it supports higher-frequency signals while minimizing attenuation across the run. The cable arrives pre-terminated and reinforced for rugged installations, indoors or out.

How does this cable preserve signal quality over 40 feet?

The KMR240 dielectric and solid copper conductor reduce resistance and energy loss compared with generic coax, so you retain stronger signal levels at the far end. The 50 Ohm impedance matches common RF devices, avoiding reflections that harm performance.

• KMR240 low-loss construction for reduced attenuation
• Solid copper inner conductor for efficient transmission
• 50 Ohm impedance for RF compatibility with antennas and routers
• Pre-terminated SMA male to SMA female connectors to limit connector loss

Will it work with my router, ADS‑B or cellular antenna?

Yes — the SMA male to SMA female pairing is a standard extension for many consumer and hobbyist RF devices. It’s suitable for routers, ADS‑B receivers, Wi‑Fi antennas, cellular boosters, and many GPS or radio modules that use SMA connectors.

• Compatible with devices using SMA male or SMA female antenna ports
• Works for Wi‑Fi, 3G/4G LTE antennas, ADS‑B and many RF receivers
• Useful when relocating a device for improved reception

How durable is the cable for outdoor or harsh environments?

The cable features a flexible PVC jacket designed to withstand exposure and repeated handling. Termination points are heat-shrunk and bonded so the connector assemblies remain secure under stress and weathering.

• Water‑resistant PVC jacket for outdoor use and flexibility
• Heat-shrink tubing with adhesive lining reinforces connector joints
• Professional crimp and bonding methods to prevent connector separation

How easy is installation and what should I check before connecting?

Installation is straightforward: rotate the SMA male onto the device’s SMA female, ensure firm hand-tightening, and avoid over-torquing. Check connector types and device impedance before connecting to prevent mismatch.

• Hand-tighten SMA connectors; use a small torque wrench if specified
• Confirm device uses SMA and 50 Ohm specification for best results
• Avoid sharp kinks and secure the cable to prevent strain at terminations

Who is this for: This 40-foot XRDS -RF extension cable is aimed at hobbyists, network technicians, and anyone relocating antennas or RF modules—especially where a longer run is needed without large signal penalties. It’s a practical choice for home Wi‑Fi upgrades, ADS‑B setups, cellular signal boosters, and outdoor antenna installations where durability and low loss matter.
