Precision 75Ω Miniature Coax for High-Density RF Coax

The RG179 is a 75Ω miniature coaxial cable engineered for applications where low capacitance, stable signal integrity, and compact size are essential. With a jacket diameter of only 2.54 mm and a weight of just 15 g/m, it brings true 75Ω performance to spaces where standard cables cannot fit. Its solid PTFE dielectric delivers higher voltage withstand and long-term stability, while the FEP jacket provides excellent chemical resistance and a low-friction surface. The stranded silver-plated copper clad steel inner conductor combines high tensile strength with low high-frequency loss, making the RG179 ideal for both fixed and semi-flexible installations. Whether you are routing video inside a medical endoscope, feeding a 75Ω SDR receiver, or connecting a broadcast test instrument, the RG179 delivers reliable performance from 0.1 GHz to 3 GHz in temperatures up to 200°C.

RG179 Coax Construction

Why Choose Our RG179?

• True 75Ω Precision – Designed specifically for 75Ω systems, ensuring low VSWR and optimal signal transfer for video, broadcast, and instrumentation.

• Low Capacitance for Signal Integrity – 64 pF/m capacitance preserves fast edges and reduces high-frequency roll-off, critical for video and pulse signals.

• Solid PTFE for High Voltage and Stability – 1200 VRMS rating and excellent long-term stability, even at elevated temperatures.

• Miniature and Lightweight – 2.54 mm OD and 15 g/m weight enable routing in space-constrained and weight-sensitive applications.

• High Flexibility – 10 mm bend radius and stranded conductor allow complex, space-saving installations.

• High-Temperature and Chemical Resistance – FEP jacket and PTFE dielectric survive -55°C to +200°C and resist oils, acids, and moisture.

• Practical Power Handling – Up to 791 W at 0.1 GHz and 144 W at 3 GHz in a 2.54 mm cable, suitable for many low-power transmit and receive applications.

• RoHS Compliant – Manufactured with environmentally responsible materials.
