Antenna Termination Box
thingiverse
Termination box for antenna runs is a must-have. Double sided SO-239 connectors, like these found at https://www.aliexpress.com/item/32792422079.html?spm=a2g0s.9042311.0.0.5bef4c4d9PQi8N, are ideal for this task or single sided ones can be used if that's what you prefer. I'm using them for a "quick" disconnect of antennas inside the shack when thunder storms approach. The 2, 4 or 6 port versions work great. Here's an example of how I set up my 6 port version. Pictures will follow soon as I finish installing it next weekend - hopefully! To add text for your port names, use a text object in your favourite CAD program.
