I watched a video on the Ham Radio Crash Course about this very tiny and relatively easy-to-build antenna a few months ago and bought one right away from Amazon. It only took about 30 minutes start to finish, the hardest part being attaching the surface mount capacitor as the video describes. I have since use it pretty much exclusively when activating the in the field. I even had a SOTA SSB QSO with Adam, K6ARK, himself during a SOTA activation at Smith Rock State Park!
I am using 18 gauge wire cut for 20M. I used my NanoVNA to tune and marked 10-20M on the wire with various colors of shrink wrap to differentiate the bands. I have a second length of wire that I added banana clips to connect so I can get up to 40M if I want to. If I want to use a new band I unroll from the Buddipole wire holder to the marking and check the SWR function on the IC-705 in the field and so far have had pretty good success. I've done several POTA and SOTA activations using SSB with the antenna. I love how simple and portable this setup is.
This is a great DIY antenna project, it simple to build and easy to use and I'd suggest it for anyone interested in field QRP activating.
