Frequently Asked Questions
Q: Are these SMA extension cables compatible with my WiFi router or access point?
A: Yes — these 20M SMA Male to Female coaxial extension cables are compatible with most routers, wireless access points, wireless network cards, and USB WiFi dongles that feature a standard screw-on (SMA) antenna connection. Simply unscrew your existing antenna and connect it via the cable to reposition it for optimal signal.
Q: Will a 20-metre cable cause signal loss?
A: The RG174 cable used here is engineered for low-loss performance across typical WiFi frequency ranges. While some minor signal attenuation is normal over longer cable runs, the ability to optimally position your antenna usually more than compensates, resulting in an overall better signal in your environment.
Q: What is the impedance rating and why does it matter?
A: These cables feature a 50-ohm impedance rating, which is the industry standard for WiFi and wireless telecommunications antenna systems. Matching impedance ensures maximum power transfer and minimal signal reflection between your device and antenna.
Q: Can I use both cables at the same time on the same device?
A: The pack includes 2 independent cables, making them perfect for devices with dual-antenna setups (such as routers with two removable antennas), or simply to keep one as a spare.
