This Vertical dipole antenna is for HF frequencies from around 24 mhz to 29 mhz ranges of the 12, 11 and 10 meter bands. The frequency is adjustable by loosening the pipe clamps in the center of the two radials, adjusting the radials by sliding them in or out of the outer pipe to the length needed for the band you want to work, and then retighten the pipeclamps.
The basic design concept can be scaled up or down to reach other RF bands.
The antenna can also be mounted horizontally for a horizontally polarized antenna.
instructions for construction, material lists and photos of the actual build, links to my research, etc. for the vertical dipole can be found on the instructables website at: http://www.instructables.com/id/My-Experiment-in-Building-a-Vertical-Dipole-Antenn/
