A biconical antenna (20); an entry conic (34) having an entry base (40) opposite an entry vertex (38) and a termination conic (36) having a termination base (74) opposite a termination vertex (72). The entry and termination conics (34,36) share substantially the same axis and the entry vertex (38) is adjacent the termination vertex (72). The transmission line (24) is received by the entry conic (34) and terminated in the termination conic (36). Together, the entry conic (34) and the termination conic (36) phase correct energy emanating from the transmission line (24). Another embodiment of the antenna (100) comprises an entry conic (102) having at least two sub-conics (106A,108A) and a termination conic (104) having at least two sub-conics (106B,108B). Each of the sub-conics having an integer multiple of a half-angle (θ). The biconical antenna (200) may also include a multi-conductor transmission line (204), wherein the biconical antennas (230,240) are arranged in a co-linear relationship. Each of the multi-conductors is coupled to at least one of the plurality of biconical antennas (230,240).
