Description

Product Overview

The RG174 RF coaxial cable is a mainstream 50-ohm flexible RF wire. Our RG174 cable features solid workmanship, slim size and excellent flexibility. It maintains stable signals with low loss during long-term operation, serving as an ideal choice for short-distance RF transmission. It is highly compatible with most conventional RF connection scenarios and offers superior cost performance.

 

Structural Features

This RG174 RF coaxial cable adopts a standard layered coaxial structure, consisting of an inner conductor, insulating layer, shielding layer and outer sheath with a compact and regular layout. The precision single-layer shielding design effectively blocks external electromagnetic interference. The thickened and wear-resistant outer sheath is bend-resistant and anti-aging. The integrated molding process enhances the overall toughness of the RG174 cable, preventing breakage and adapting to frequent bending scenarios.

 

Core Specifications

The parameters of our RG174 RF coaxial cable comply with universal industry standards and fit most RF equipment. It has a standard characteristic impedance of 50 ohms to meet conventional RF transmission needs. With an outer diameter of about 2.8mm, the cable is compact and space-saving. Its working frequency ranges from 0 to 2GHz for daily wireless transmission. It features stable voltage resistance and a wide temperature adaptation range of -20℃ to 80℃. All RG174 cables are strictly inspected before delivery with accurate and consistent parameters.

Working Principle

The RG174 RF coaxial cable realizes efficient signal transmission based on the coaxial transmission principle. The inner conductor transmits RF signals, and the insulating layer isolates internal and external structures to avoid signal crosstalk. The shielding layer locks internal RF signals to prevent leakage and blocks external clutter interference. The regular coaxial structure greatly reduces signal attenuation of the RG174 cable in short-distance transmission, ensuring complete, stable and low-loss signal delivery.

 

Application Scenarios

The RG174 RF coaxial cable is suitable for short-distance wireless transmission in multiple fields. It is widely used for GPS and WiFi antenna connection and wireless module signal docking. It adapts to laboratory testing instruments, small communication equipment and IoT sensor devices, as well as civil and industrial scenarios such as vehicle electronics, security monitoring and smart homes. Matched with our RF connectors and adapters, the RG174 cable delivers higher compatibility and more stable equipment operation.
