A highly compact and lightweight 82 channel all band VHF-UHF television antenna having three antenna elements wherein each element is the identical physical length and each element includes two half sections. Each antenna element is separated a predetermined distance from each other element wherein the predetermined distance is substantially less than one-tenth of the shortest wave length in the VHF band. A first set of coils are utilized to electrically lengthen the halves of the two elements for reception in the VHF band and a second set of coils are utilized to provide proper delays between the signals received by each antenna element so that when the signals are combined the signals are substantially additive and in phase. The antenna system includes a weatherproof housing containing a rotor, a preamplifier, and electronic circuitry. A deloading mechanism is arranged around the housing to engage the circumference of each antenna element to provide stability under the driving forces that may occur in the atmosphere.
An apparatus for receiving first signals from a first antenna element having first and second end-driven half sections and second signals from a second antenna element having first and second end-driven half sections, said first and second antennas being spaced apart in the same plane, said apparatus comprising:
