Wow, I couldn't believe my eyes what a 2.5 foot cord has to do with electricity! 14% power dissipation, that might seem reasonable considering I'm just using it as a walkie talkie antenna, but I used it with my meter. , the only reason I bought it was because I needed 2 male SMAs for the PL259. My other is only a foot long but thinner and loses almost no strength to perform any given test. SWR calculation over 5.2!
