While there is no "perfect" antenna, this simple, proven design for a monoband HF vertical using a 1/4 wavelength vertical radiator and four, 1/4 wavelength sloping radial wires comes very close to being a foolproof design that will give you many hours of operating pleasure.  In effect, this antenna is a variation of the familiar ground plane antenna seen in many omnidirectional VHF and UHF antennas.  A ground plane antenna designed for any HF band from 20 meters to 6 meters should work very well with locally made materials. I have a 20 meter version of this antenna fed with RG-8 coaxial cable, and it works quite well, considering the poor state of HF propagation these days.  I use an old Drake MN-4 antenna "tuner" to reduce the small amount of SWR found in this antenna.
