Each Model J-275D-K-* consists of a wide-band, diamond-
loop driver, two vertically spaced reflectors and 13 tuned
directors. The diamond driver is an exclusive TACO design
providing a matched 75 Ohm impedance throughout the
UHF range. Dual reflectors increase both horizontal and
vertical directivity of the driver and provide front-to-back
ratios of 20 dB or better. Directors are tuned for specified
channels to provide gain of 14 dB over a reference dipole.
