Feeding Antennas Through Window

I have a habit of doing some “temporary” things that turn out to be not temporary. One example is putting an antenna feedline through a window. I have a 2nd story window in my garage where I wanted to pass some antenna feedlines. This window would never really have to be securely closed, so if I could find a way to seal the window from the weather, with my feedlines passing through, I would be all set.

I wanted to pass some feedlines through a window, with a weather seal, without modifying the window hardware. I decided to create a modular 3D printed feedline bracket, customized to fit my windows. Note, these are Anderson series 200 windows, which are fairly common. I did customize the bottom of the bracket for this window, so if you have something different, it is possible that changes would be required.

In order to span the entire width of the window, several pieces are required. I made one bracket for coax using SO-239 connectors, one for wires or window line using feedthrough insulators, and spacers to extend the bracket out to the edge of the window. A series of interlocking “ears” were used on the sides of the brackets. No fastening hardware is required if you span the entire window width.

Here are some pictures of the wire feedthrough bracket:

I will post pictures of the other pieces and the completed project in the near future. I will also put this project’s 3D printer files on PRINTABLES.COM If you have a 3D printer and have not looked at PRINTABLES, you need to check it out. You would not believe the number of printable models there, including many for Ham Radio applications.
