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.

*Where interfering signals such as co-channel, adja-cent channel and ghosting are present, custom arrays can be designed to reduce the level of interference by as much as 40 db in most cases.
A qualified structural engineer should be consulted prior to mounting an antenna on a tower or a support structure.
