XRDS -RF SMA Male to SMA Female 50ft Coax Cable

XRDS -RF 50ft SMA male to SMA female KMR240 coaxial extension cable delivers a 50 Ohm, ultra-low-loss link for antennas, routers, receivers and RF test setups.

This 50-foot SMA extension uses KMR240 low-loss coax and SMA male / SMA female connectors to extend antenna runs without introducing significant attenuation. Built with a solid copper center conductor and a durable PVC jacket, it balances signal retention and outdoor durability so you can place antennas or test gear farther from your equipment while keeping connections reliable.

How much signal loss should I expect over 50 feet?

The KMR240 dielectric and solid copper conductor are chosen to minimize insertion loss across cellular and WiFi bands. Expect markedly lower attenuation than standard RG-58 at the same length, making it suitable for 3G/4G/5G and many RF applications.

• 50 Ohm characteristic impedance for consistent matching.
• Low-loss KMR240 construction designed for high-frequency use.
• Solid copper inner conductor to reduce resistance and loss.
• Length: full 50 feet to place equipment optimally without excessive signal drop.

Will the connectors stay secure outdoors or during handling?

Connectors are heat-shrink sealed with adhesive-lined tubing at each termination to prevent separation or moisture ingress. That reinforced junction reduces the chance of connector detachment and adds a layer of weather resistance for outdoor runs.

• Heat-shrink tubing with adhesive lining on both ends.
• Factory-attached SMA male and SMA female terminations.
• Robust strain relief where connector meets cable prevents pull-off.

Which devices and systems is this cable compatible with?

The SMA male to SMA female configuration pairs common radio equipment with external antennas, signal boosters and receivers. It supports many RF services such as cellular, WiFi, ADS-B and ham radio systems when 50 Ohm matching is required.

• Cellular modems, 3G/4G/LTE/5G antennas and boosters.
• WiFi routers, WLAN antennas and access point extensions.
• ADS‑B receivers, GPS modules, ham radio and general RF test rigs.
• Any device needing a 50 Ohm SMA male-to-female extension.

How durable is the cable for outdoor or harsh environments?

The outer jacket is a flexible, water-resistant PVC blend designed to withstand repeated handling and outdoor exposure. While not a sealed submersible cable, the combination of water-resistant jacket and adhesive-lined heat shrink improves longevity in exposed installations.

• Flexible PVC jacket resists abrasion and UV to extend service life.
• Adhesive-lined heat shrink reduces moisture migration at terminations.
• Suitable for rooftop, mast or ground-level runs with proper routing.

Who this cable is for: installers, RF hobbyists and wireless professionals who need a reliable 50-foot SMA extension with low insertion loss for cellular, WiFi, ADS‑B, ham radio or RF testing. It’s a solid choice when you must move an antenna or test device away from equipment without compromising impedance match or introducing excessive signal attenuation.
