Description
High-Performance 50-Ohm Low-Loss Flexible Coaxial Cable
Premium 0.195-inch low-loss coaxial cable sold by the foot, engineered as a drop-in replacement for RG-58 and RG-142 in LMR, GPS, SCADA, and antenna jumper assemblies.
The Purchase Radios PR195 (RFC-195) is a commercial-grade 50-Ohm low-loss coaxial communication cable engineered for high-frequency signal integrity, low attenuation, and long-term outdoor durability. Built around a high-conductivity 0.94 mm solid bare copper center conductor, foamed polyethylene dielectric, and a dual-shielding structure consisting of 115% overlapping bonded aluminum foil alongside a 90% coverage tinned copper braid, PR195 achieves superior RF shielding efficiency (>90 dB) from 1 to 1000 MHz.
Designed as an upgraded, low-loss drop-in alternative to standard RG-58 and RG-142 cabling, the Purchase Radios PR195 features a flexible, UV-resistant black PVC outer jacket rated for 20 years of continuous outdoor service across temperature extremes from -40°C to +85°C. With a tight 12.70 mm minimum bend radius and a 4.95 mm outer diameter, PR195 provides easier handling and routing than rigid corrugated hard-line cables. Sold conveniently per foot, it serves as an ideal solution for short antenna feeder runs, mobile antenna installs, SCADA systems, WiMax/WLAN infrastructure, and custom RF jumper assemblies operating under FCC Licensing standards.
