The HyEndFed antenna is momentarily my only HF antenna. Just 11,85 meters long (38.878 ft), very stealth, and a great performer. It was much better than my dipole. And it absolutely outperformed all my verticals I've had. The antenna is made for 40-20 and 10 meter. A high quality Dutch product. Of course when someone is handy you can made it yourself. But I know my restrictions and capabilities for technical skills. I tune this antenna with a MFJ-925 for all other HF bands. On 40, 20 and 10 meter I don't need a tuner. I know, a perfect SWR says nothing about the effectiveness of the antenna. Nevertheless, here are my SWR readings on the other HF bands with the HyEndFed.
Maybe I replace the 6 meter antenna, after the Es season, for a ground plane antenna for 30 meters.
