An active biconical antenna and a receive array comprising a combination of active biconical and Vivaldi antennas. In one configuration, the active biconical antenna includes upper and lower cones. Each cone has a respective truncated apex. First and second feed points are respectively connected to the truncated apexes of the upper and lower cones and to first and second conductors. The active biconical antenna further includes a buffer amplifier having respective input terminals connected to the first and second conductors. The buffer amplifier has an input impedance that is impedance matched to an antenna impedance at and above but not below a frequency fc and is higher than the antenna impedance at frequencies substantially less than fc. The buffer amplifier also has an output impedance that is impedance matched to a system impedance at frequencies both above and below fc. A length of the first and second conductors is less than a wavelength at the frequency fc.
