95% efficient EFHW transformer with wire winder.

Folks asked in the comments for me to detail my End Fed Half Wave matching unit, so I did some things to make it more consumable. It's nice to have your wire winder and matching transformer be part of the same unit. It's also nice to use a small core with a small aperture to get really efficient results from that unun when you're running QRP.
