A dual stacked rooftop corner reflector antenna for UHF television reception from 1954. Corner reflector antennas were widely used for reception of analog UHF TV channels, from 470 to 890 MHz. Each of the two stacked halves of the antenna consists of two bowtie dipole driven elements in front of a reflector made of two flat wire screens joined at a 90° angle. The triangular "bowtie" shape of the driven elements gives them a wide bandwidth to cover the UHF band. Using two stacked antennas doubles the horizontal gain, increasing it by 3 dB, reducing reception of ground and sky noise.
