Hangzhou Putianle Cable has released its 2026 RF Coaxial Cable Selection Manual. The 340-page document covers 17 product series and 325 models, making it the most complete technical reference the company has published.
The manual is organised by impedance, size and construction. Each model has its own page with four groups of data: structure (inner conductor, dielectric, outer conductor, jacket and their dimensions), electrical performance (characteristic impedance, velocity of propagation, nominal capacitance, peak power, maximum frequency, VSWR, insulation resistance, breakdown voltage and PIM), mechanical and environmental performance (bending radius, tensile strength, weight, jacket material, operating temperature and standards), and an attenuation and power table with nominal dB/100 m values from 100 MHz to 5 GHz.
Unlike a simple specification sheet, the manual lists the attenuation curve for every model, so engineers can estimate link budgets during selection instead of waiting for samples. Applicable standards are stated for each series, including IEC 61196, GB/T 14837 and YD/T 1092.
A new Downloads page on the official website provides the manual as a PDF, protected by a download password available from the sales team. The 325 product pages on the site use the same dataset, so structure tables and attenuation curves can be viewed directly.
Founded in 2003, PTL manufactures RF coaxial cables, fiber cables and optical components and exports to more than 30 countries. To request the manual, contact sale@ptlcable.net or call +86 159 6711 5540.
