The model allows multiple camera connections to be grouped in a single compact box, improving cable management, reducing clutter, and providing a cleaner and more professional installation. It is suitable for setups where coaxial or UTP…
This is an alternate take on the ugly balun/RFI choke. I don't like random pipes and wires and equipment hanging around haphazardly. Eventually I made some real baluns and this made it into the "abandoned projects" bin, but it was a good…
Overview This is a QRP balun housing I've been working on. It's nothing new in terms of what it can do, but it's a nice, compact package that requires only minimal hardware and is easy to assemble. I'm planning to use this in conjunction…
This is a tiny clip designed to help in winding an air core choke balun (a few loops of coaxial cable which reduce common mode currents). See here for more information on this. The clip is symmetrical (print twice to get a pair). Put…
Thanks to Lukáš OK1ECH and his excellent universal balun/unun box. I wanted to make a RF choke (or 1:1 unun), and since he posted the f3d file, it was easy to update to add two coax ports (SO-239 or similar). I also changed it to M3…
interior dimensions are 55mm X 70mm X 32mm. Holds a 140-43 toroid with a little extra room for thick coax or wire if needed. uses m3 screws all around to mount the end connectors and to secure the lid. Great for those in the ham radio…

Just a simple case for the Nooelec Balun OneNine V2.0. The PCB fits over some small posts- these can be melted a little with a soldering iron if you want to secure the PCB in the case. However the lid does a pretty good job of this when…
I wanted to integrate a Balun into my antenna spool for a long time, now it is here! I created this antenna winder for SOTA activations, but of course you can use if for non-sota activities as well. The balun I wound has a 1:64 ratio, but…

This is a 3D printed 1:1 air choke balun based on a design from W6NBC, which I can't find the original model for, so, I attempted to make my own. I don't have any testing equipment to make sure it's actually working, so any suggestions…
I have a 53-foot long wire antenna I use for portable ham radio. Used with this unun, it works surprisingly well, but winding it up when I'm done was a pain, so I designed this to mount to the back of the unun. This uses an M8 bolt, nut…
