ABSTRACT:
A dipole antenna adjustable in span and distance to the reflector provides higher gain reception for a television receiver. By maintaining the ratio of span to distance constant optimum tuning is possible over a given band of frequencies. Tuning adjustment control is obtained from behind the reflector to eliminate interference with the radiation pattern of the antenna. BACKGROUND OF THE INVENTION
