ABSTRACT:
Field Configurable Radiation Antenna Device for fixed dipole antenna comprising of a hollow tube and at least one pair of directional vanes is described. The beam direction of the antenna can be changed by operationally connecting multiples pairs of directional vanes to the hollow tube and by rotating the directional vanes relatively outer peripheral surface of the hollow tube. Such adjustments allow the user to tune the antenna to meet new or unforeseen coverage issues.
