With feet of wire, a Flat-top or Inverted-V are about the only support options available. Just keep the vertical radiator in the clear and the wire as high as possible. This antenna is optimized for the lower bands. RG-8X or Super is recommended for most installations.

Think of the "Carolina" windom antenna the modern version of the windom as an "upside down vertical antenna", hanging down from its counterpoise strung more or less horizontally some 10 meters or more above ground. In other words, the 22 feet vertical component of the "Carolina" - between the matching voltage transformer and the current choke balun - is a vertical antenna, fed at the tip. This vertical does not require a ground or a system of radials! Because the antenna is not fed at its center, the RF currents in each horizontal radiating section are very much unequal. This makes the vertical coaxial feedline radiate RF energy. Normally, in the case of normal balanced dipoles, we try to avoid this from happening. By letting it do so, the outer shield of the 22 feet long vertical coax RG-8X radiates to fill in the gaps in the signal pattern radiated by the top portion of the antenna.
I didn't know either, but I wanted to find out. Many people hold endless debates in forums, model until the cows come home and debate some more on this topic. If that's what turns you on, great! It doesn't work for me. I use a different approach.
Here is my home HF antenna. It is an off centre fed dipole, with 10 feet of vertical radiator. It needs no tuner on 40m, 20m and 10m. It also works fine on all bands above 40m with a tuner, and even below 40m on 60m, and 80m, although the coax losses will be higher.
