RG144U M17/62 is a MIL-DTL-17 compliant 75 Ohm high power coaxial cable engineered for high impedance RF transmission applications where lightweight construction and high voltage rating are critical. This 75 Ohm RF cable features a 1.33mm stranded silver-plated copper-clad steel (SCCS) inner conductor and fluoropolymer dielectric, delivering exceptional electrical performance with 72.2 pF/m capacitance and 69.5% velocity of propagation. The single silver-plated copper braid shield at 8.38mm provides reliable EMI/RFI protection, while the unique silicone-coated fiberglass double braid jacket at 10.4mm offers superior thermal stability and abrasion resistance up to +200°C. With 3700V operating voltage and 3 GHz frequency capability, RG144U is the preferred choice for CATV distribution, broadcast transmission, CCTV systems, antenna feeders, and high voltage RF applications where 75 Ohm impedance and rugged jacketing are required.
75 Ohm impedance – Industry standard for video, CATV and broadcast transmission systems
3700V operating voltage – High voltage rating for antenna feeders and broadcast transmitter installations
Stranded SCCS conductor – Silver-plated copper-clad steel stranded construction combines flexibility with high tensile strength

Q: What is the M17 part number for RG144U?
A: M17/62-RG144U is the official MIL-DTL-17 compliant part number for this 75 Ohm high power coaxial cable.
Q: What is the impedance of this RF cable?
A: 75 Ohms – the industry standard for video, CATV and broadcast transmission systems.
Q: What is the maximum frequency of this 75 Ohm coax?
A: 3 GHz (3,000 MHz), suitable for CATV distribution, satellite IF downlinks and broadcast applications.
Q: What is the operating voltage?
A: 3700 Vrms – significantly higher than most commercial 75 Ohm coax cables, making this MIL-DTL-17 RF cable a preferred choice for high voltage installations.
Q: What is the temperature range?
A: Continuous operation from -55°C to +200°C. Unlike standard PVC-jacketed coax cables that soften or crack, this high power coaxial cable uses a silicone-coated fiberglass double braid jacket for extreme thermal stability.
Q: What is the outer diameter?
A: 10.4mm including the silicone-coated fiberglass double braid jacket – a rugged yet lightweight construction.
Q: How does RG144U compare to RG59 or RG6?
A: RG144U is a true MIL-DTL-17 compliant high power coaxial cable with a 3700V voltage rating and -55°C to +200°C temperature range. Standard RG59 and RG6 are commercial grade 75 Ohm coax cables with PVC or PE jackets, lower voltage ratings, and narrower temperature ranges. For mission-critical broadcast or defense video applications, RG144U is the superior choice.
Q: What connectors work with this 75 Ohm coax?
A: BNC, TNC, N-Type, and F-Type connectors designed for 10.4mm diameter 75 Ohm cables.
Q: Is this RF cable suitable for outdoor use?
A: Yes, the silicone-coated fiberglass double braid jacket provides excellent weather resistance, UV protection and abrasion resistance.
Q: Do you offer custom lengths?
A: Yes, we accept OEM & ODM orders. RG144U M17/62 is available in bulk spools, cut pieces, or fully assembled with connectors.
