I designed this to connect an EFHW to a sotabeams tactical mini mast.  This allows the antenna wire to freely flow on the mast tip without snagging and so the EFHW to be adjusted based on conditions to inverted L, sloper, inverted V with varying distances from feed to mast.

Also works on a Tactical 7000hds mast and maybe others. The Freecad file is attached so you can adjust the mast hole diameter.

New version 06-May-2024 that works with Tactical Mini, Tactical 7000hds (L side) and Carbon-6 ultra-light (S side). More compact too !
