XRDS -RF 35ft SMA Male to SMA Female Coax Cable | 50 Ohm Low-Loss KMR240 for SDR & Ham Radio

Overview

The XRDS -RF 35ft SMA Male to SMA Female Coax Cable is built for reliable, high-frequency signal paths. With 50 ohm impedance and a 35-foot length, it provides a practical balance between reach and signal integrity for SDR setups, HAM radios, and network antenna configurations.

Premium build for real-world use

The inner conductor uses solid copper, selected for efficient conduction and minimal loss. The jacket is a flexible, water-resistant PVC designed to withstand outdoor environments, while the outer design integrates a black heat-shrink tube and adhesive to create durable, bonded connections that resist accidental detachment during handling or setup.

Low-loss performance you can rely on

• Impedance: 50 Ohm, optimized for RF transmission across a wide range of frequencies.
• Ultra-low loss: at 3000 MHz, signal loss is only about 0.42 dB per 3 feet, helping maintain signal quality over the full length.
• KMR240 coax design: supports higher-frequency use with minimal degradation over the 35-foot run.

What you can connect

This cable is designed to link SMA equipment to SMA female antennas, making it suitable for a variety of systems and devices. Typical applications include SDR receivers, ham radio setups, ADS-B receivers, GPS antennas, 3G/4G LTE antennas, WLAN/WiFi devices, and other radio transmitters and signal booster configurations.

Why choose XRDS -RF for your setup

• Solid copper core and 50 Ohm impedance for dependable RF performance.
• Durable, outdoor-ready jacket and robust connector protection to reduce wear and disconnects.
• Long 35-foot length minimizes the need for repositioning while preserving signal integrity.

Note: Benefits described here reflect design intent and published specifications. Real-world results depend on overall system design and operating conditions. This product offers a robust option for expanding your antenna and transmission setups with flexibility and reliability, rather than guaranteeing a particular outcome.
