HIGH BAND ANTENNA

A single high band model provides optimum per-
formance over the entire VHF high band. This
sturdy antenna gives excellent performance with
reliable, trouble free operation. A newly designed
feed point accepts a standard 75 Ohm CATV
housing connector.

Please Note: dBi = dBd + 2

UHF LOG PERIODIC ANTENNA
MODEL:

• J-275D-K-*

Each Model J-275D-K-* consists of a wide-band, diamond­loop 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, adja­cent 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.
