Our jumpers are nulled to ¼ wave @ 27 MHz for optimal performance and less reflect. We use iONKY silver plated Teflon pl259 connectors. That are soldered in and then heat shrunken. Proper jumper length matter a lot when running coax you’ll see less reflect and be resonant on the band you intend to use. A resonant antenna and coax system makes a huge difference.
