I finally got this antenna in the air today, at the Parker Radio Portable "Rodeo". Took longer than I expected to set up, and I'm pondering what improvements I can make in that regard, but in the end, I think there's not a lot of room. With ~66 ft. of wire, and only 28 ft. of elevation using a telescoping mast, it takes about 60 ft. of linear space - actually a bit more, since the mast bends a bit, and then there's guying at the feed end, the way I have it supported, plus the counterpoise.
Performance - I didn't end up trying to make any contacts, since the whole process of trimming it took longer than I expected. On the VNA, I got it below 1.4:1 across the 40M band, and usable on 20M. 15M and 10M were so-so. I didn't save plot images, since running the NanoVNA on my phone was, for some reason, a little wonky today. And with the sunshine, seeing the screen was a pain as well. I guess my ideal setup would involve a pop-up shelter or some other way to be in the shade.
I'll probably trim it a little more, to trade-off 40M against being a little better on 20M. It's likely I'll need a tuner for 15 and 10, and getting a Z-match kit is on my list anyway, though it's a low priority.
I don't know when I'll get out next, but I have a list of things to work on, and a better idea of what to expect. I can see why a lot of people prefer to use a coil-loaded vertical.
