"Ron Baker" <[EMAIL PROTECTED]> made an utterance to the drakelist gang ---------------------------------------------------------------------- All, regarding the coax contamination question, coming from the cable industry I have learned that all coax cable has a certain life expectancy. Small diameter coax will start to deteriorate after 10 years usually in the form of increased attenuation more noticeable at the higher frequencies. It gradually gets worse over time from that point. Large diameter coax and hard-line cable start to noticeably deteriorate after 20 years. Now the time does vary somewhat with the construction and materials in the coax. The bottom line, old coax probably should be thrown away and not used. Especially if it shows its age, not been properly stored or otherwise misused.
