“For lithium polymer batteries the under-voltage threshold is 3V” Very good idea. ---

So I have some of these N-type chassis connectors and one of the RAK antennas so I have a question. This would make an elegant outdoor gateway, the antenna anchored to the roof by the ali base and using the N chassis connector to enter an IP67 enclosure containing my @Charles’s specification Pi-Zero W + RAK831 gateway. All I need from the inside of the house is power… Result! My quesiton (to the rf gurus) ; in a perfect world, how do I terminate a co-ax cable (say SMA pigtail) to the back of this N chassis connector without being lossy? Can I carefully ground the shield to the shell exposing as little of the antenna conductor as possible? Any hints? ---

Given the number of messages in this topic I was wondering when you would start part 2. I am already getting lost when searching for something I know to have been posted here. (And search does not always work due to people posting just pictures/youtube links without a brief description) ---
