SOTA Vertical Antenna for 40-30-20m

Hi, I had promised to provide more details on my most recent antenna project for SOTA, which is a three-band vertical with a loading coil at the base. Background: I am a happy user of the 3-band EFHW with traps designed by Heinz, HB9BCB, but on some summits, the ca. 16 m of wire are difficult to deploy. On crowded summits (like skitouring in winter), you risk to annoy people by an inverted vee of that size right on the summit (and they might even take down parts of your antenna without asking)…

For an Endfed I guess the coil will make it very unefficient.
One (floating) radial will fit on every summit.
