An antenna including a metallic reflector; a radiating element disposed on the reflector; a metallic power divider disposed on the reflector; a coaxial cable interconnecting the power divider to the radiating element; and a clamp for clamping the coaxial cable to the reflector or the power divider, wherein the clamp is unitary with the reflector or the power divider. There may be multiple clamps for clamping the cable to both the reflector and the power divider as necessary to secure the cable in place. Also, there may be a plurality of coaxial cables. The clamp includes a metallic plate having an opening for receiving the coaxial cable. The opening is preferably stamped in the metallic plate. The opening is preferably substantially U-shaped and the coaxial cable is frictionally retained in the opening by a press fit. More specifically, the clamp includes opposing leg portions and a base portion which define the opening. The opening includes a substantially circular cross-section defined by the base portion and a lower end of the leg portions and a substantially V-shape tapered portion defined by an upper end of the leg portions.
