Compatibility with wireless standards & applications: Our RP-SMA extension cables' range of frequency band compatibility (from 0 to 18GHz), consistently low broadband VSWR, and impedance matching to 50 Ohm antennas and cables  makes them suitable and compliant for all the following applications:

Regarding quality and compliance, our RP-SMA extension cables are second to none. They fully comply with ROHS 3 and REACH restrictions, ensuring they are free from lead content, other heavy metals, and toxic materials. This reassures you that you're investing in a product that performs well and meets the highest safety standards.

Installing our RP-SMA male-to-female extension cable is a breeze. The RP-SMA male connector effortlessly fits the jack on most WiFi routers, while the RP-SMA female connector snugly fits the male connector on antennas with an RP-SMA male connector. This means most WiFi antennas with an RP-SMA connector have a male connector. The extension cable lets you position the antenna further from the router, optimizing the line of sight. It's a simple and quick solution for improved wireless connectivity.



Frequently Asked Questions

What is the insertion loss for the 3 ft and 6.5 ft versions of the cable at various frequencies?

The insertion loss for the RG174U cable is approximately 1.5 dB per meter at 1 GHz. For the 3 ft (0.914 meters) cable, the loss is around 1.37 dB, and for the 6.5 ft (1.981 meters) cable, the loss is about 2.97 dB.

How does the cable's performance vary in extreme weather conditions, particularly regarding its outdoor rating?

The RG174U cable is designed to be outdoor-rated, which means it can withstand UV exposure, temperature extremes from -40°C to +80°C, and moisture, ensuring reliable performance in harsh environmental conditions.

What are the maximum voltage ratings for the RP-SMA connectors and the RG174U cable?

The RP-SMA connectors typically have a maximum voltage rating of around 335 V RMS, while the RG174U cable itself can handle voltages up to 1,400 V peak.

Can this cable be used for high-frequency applications, such as 5 GHz Wi-Fi or microwave frequencies?

Yes, the RG174U cable can be used for high-frequency applications, but with increased attenuation at higher frequencies. It is more suitable for short-distance applications at frequencies up to 18 GHz due to higher insertion loss at these frequencies.

How does the cable's shielding effectiveness compare to other coaxial cables in its class?

The RG174U cable provides moderate shielding effectiveness, typically around 40 dB. For applications requiring higher shielding, cables with double or triple shielding, like RG58 or LMR200, might be more appropriate.

What are the tensile strength and bend radius specifications for the RG174U cable?

The RG174U cable has a tensile strength of approximately 100 pounds (45 kg) and a minimum bend radius of 1 inch (2.5 cm), allowing for flexibility and durability in installation.

Are there any specific installation guidelines to ensure optimal performance of the outdoor-rated cable?

To ensure optimal performance, avoid sharp bends exceeding the minimum bend radius, secure the cable with UV-resistant ties, and use weatherproofing materials on connectors to prevent moisture ingress.

How does the dielectric material of the RG174U cable affect its performance in terms of velocity factor and signal propagation?

The RG174U cable uses a solid polyethylene dielectric, providing a velocity factor of 0.66. This affects signal propagation speed, with the signal traveling at approximately 66% of the speed of light in a vacuum, which is standard for cables in this class.
