Here are some comments from "Bucktail Outdoor Resources":

NanoVNA SWR Tested Amateur Radio antenna based on a chalk line reel and copper wire. This may be the least hassle way to set up an HF / Shortwave antenna without a tuner in the field, without adding extra weight. QRP only unless you use a larger 49:1 or 64:1 transformer.
