    "content": "My very first outdoor antennas were connected via Belden 9913, and with\nextreme care in installing the N connectors onto the end and to the\nantennas, they stayed watertight until a couple of years later when I\naccidentally ran a drill into the feedline while trying to enlarge the hole\ninto the house for more runs of coax. But many people have problems with\nwater accumulation in Belden 9913 type air dielectric coax so I don't\nrecommend it. I switched to using LMR-400 and have been pleased with its\nperformance in an installation that was up without problems for over 10\nyears. (Never had problems with it, just tore it all down after about 10\nyears to move from Minnesota to Texas!) As others have mentioned, LMR-400UF\n(Ultra-Flex) is an option for less stiffness in the rotator loops.\nPersonally, I'd go ahead and use the regular LMR-400 and leave generous\nrotator loops, and you should be okay. That's how I put together my station\nin Minnesota and like I said, I had no problems with the coax in 10 years'\ntime, before taking it all down to move to a new state. The Ultra-Flex\nversion has noticeably greater loss than the regular LMR-400, especially in\na 50-foot run on the 70cm (or higher) band. You might compromise by using\nLMR-400UF from the antennas to the rotator loops to just below the top of\nthe tower, then change to regular LMR-400 from there to the rest of the 50\nfoot run to the radio location. You could even use a short piece of\nLMR-240UF for the rotator loop and then regular LMR-400 for the rest of the\nrun, if you weren't comfortable with the stiffness of your loop.\n\nGood luck with your installation.\n73 de W0JT/5, EL09vu20, AMSAT-NA LM\n\nOn Fri, Feb 17, 2017 at 2:46 PM, Norm n3ykf <[email protected]> wrote:\n\n> Belden 9913f7\n>\n> On Fri, Feb 17, 2017 at 3:17 PM, Frank Staffa Jr. via AMSAT-BB\n> <[email protected]> wrote:\n> > Hello everyone.
