Tactical End Fed antenna winder
thingiverse
End Fed support for 240 size toroids, suitable for EFHW antennas. - 2 versions available for BNC or SO239 connectors - the spool can easily accomodate more than 20 meters of AWG20 wire, to build a full size 10-15-20-40m EFHW antenna - easy to build (pictures are self-explaining) - size of heat-shrink tube is 60 mm (diameter), 98 mm (flat). Nylon or other high temperature material is recommended if you chose to put the heat-shrink tube (black version is MJF PA12 industrial grade Nylon) My builds are made according to standard EFHW projects with FT240-43 toroid and 100pF high voltage capacitor, I use them up to 100w SSB without issues. My favorite solution is with "split" 10+10m of wire (with faston or equivalent connector), so I can use a short 10m antenna for 10-15-20m and deploy 20m of wire to cover 40m band only when needed.
