Description

The Ugly Bow Tie is a simple but useful spool for building your own End Fed Halfwave antenna. The frame is designed to accommodate an FT 114-43 ferrite ring and a BNC coax connection. That ferrite is rated for 20 watts but if you stack two you can make it to 100 watts.  I may model one for the SO-239 connection but for the time being this is it.  It will hold at least 65' on one side. There are plenty of holes for strain relief and small carabiners on the corners. Good luck with your build!! 

 

I recommend using PETG. I havent had any issues with durability with the current settings.
