Introduction
RG174 coaxial wire is a thin, flexible RF cable that is commonly used in compact electrical and communication systems where space is limited and lightweight cabling is required. RG174, known for its tiny diameter and ease of routing, is widely used in Wi-Fi devices, GPS modules, antennas, IoT equipment, and test instruments.
Despite its compact appearance, RG174 provides dependable signal transmission for low-power RF applications over a wide frequency range.
What is RG174 Coaxial Cable ?
RG174 is a 50-ohm coaxial cable having a stranded center conductor, dielectric insulation, shielding, and a protective outer jacket. Its small size makes it excellent for brief RF connections within devices and enclosures.
It is especially popular in applications that value flexibility and ease of installation over ultra-low signal loss.
Construction Structure of RG174 Cable :
RG174 coaxial wire has the following layers:Inner Conductor
- Stranded or tinned copper.
- Enhances flexibility and vibration resistance.
Dielectric Insulation
- Solid polyethylene (PE)
- maintains constant impedance.
Shielding
- Single-braided copper or tinned copper shield
- Offers EMI and noise shielding.
Outer Jacket
- PVC, FEP (Teflon)
- Prevents mechanical and environmental damage.
Types of RG174 Coaxial Cables :
RG174 cables are offered in a variety of options based on jacket material, conductor type, and compliance needs.1. Standard RG174 (PVC jacket)
- Most popular version
