Such antennas are primarily to be used in person-portable / rucksack-portable activations of parks, hills and mountains, islands and lighthouses in the various amateur radio outdoor award schemes. They would also be ideal for Field-Day operations, either as the main antenna for a single-op entry, or as an alternative antenna for multi-op entries. Of course, the same antenna designs can also be used at a home QTH - just use more substantial fittings and support structures.

The tools included in each designer page enable displays of radiation patterns, VSWR curves, antenna current diagrams, and Smith charts - all calculated and displayed dynamically for the antenna you design. No other website offers such an extensive set of tools to check your antenna design.

These are really cool! I've been meaning to get a 6m antenna ever since I got my IC-705. Now that this page has taught me about the hentenna, I think I might build one.
