(800) 463-1607 [email protected]www.wadeantenna.com 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. ** - see Gain curves UHF LOG PERIODIC ANTENNA MODEL: • J-275D-K-* SPECIFICATIONS: ELECTRICAL Specification J-275D-K-* CHANNELS 14 Thru 83 (6 models) GAIN 14 dBi (see chart) IMPEDANCE 75 Ohm VSWR 1.5:1 FR:BK RATIO 20 dB POLARIZATION H or V H.
