In the German QRPForum someone mentioned a group of QPR enthusiasts QRPGuys. They have some neat QRP kits - transceivers as well as antenna-tuners.

I gave these kits a try: QRPGuys Portable Tri-Band Vertical Antenna and the QRPGuys 40m-10m UnUnTenna Plus   

This post deals with the second one - the QRPGuys 40m-10m UnUnTenna Plus.
