Flexible braided coax coaxial cable drawing - RF CafeProperties of standard coaxial type cables have been very much standardized for many years. Unless you buy rogue stock from a supplier, if you abide by the manufacturer's application guidelines, there should not be any surprises. Do not make a bend of smaller recommended radius, do not expose the cable to excess temperatures, vibration, mechanical stress, or chemicals. Be absolutely certain to attach the coaxial cable into a properly designed connector, printed circuit board, or other type termination, paying careful attention to insulation and dielectric strip lengths, solder temperatures and dwell times, and shielding preparation. Do all that, and you will be assured a long lifetime from your cable system.

Note that attenuation values are given at 400 MHz, but can - and do - often have significantly different values at other frequencies. Always check with a coaxial cable vendor for values specific to the type you plan to use.

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ...
