If you like the concept but don't have the space, consider the half-square instead. It fits in the same space as a flat top half wavelength dipole but puts out a vertically polarised low angle signal. This makes it a good DX antenna for bands like 40 or 80 metres. Radiation direction is towards and away from you.
The bottom of the vertical elements of the half square can be quite low to the ground. Only 1 or 2 metres is OK. This low height requirement makes the half square more attractive than many other low band HF antennas, especially for DX working. Construction is super simple with two appropriately spaced supports. Just keep it as symmetrical as possible.
