A low-coast, lightweight, low wind load, broadband, foldable / deployable base station antenna has been developed using dual parabolic cylindrical reflectors with a novel small size broadband feed. The new base station antenna is easy to assemble and disassemble. The parabolic cylindrical reflector surfaces are replaced by a group of narrow rectangular plane panels. The new feed antenna is linearly polarized. It can be easily modified in order to make it sensitive to two perpendicular polarizations. This can be achieved by combining two orthogonal antennas with a common feed point. Dual polarization can also be accomplished by using two orthogonal antennas with two different feeds for MIMO configurations. The new base station antenna covers a frequency band from 450 to 960 MHz with 72% bandwidth. It can cover the frequency bands of 450 and 700 MHz WiMax, UHF DVB-H, CDMA and GSM.
