The DCR-Q was born out of a request to develop a side-mount antenna to
support 9 FM stations. Its quadrapole design is an evolution of the popular
Dielectric DCR-M antenna. The DCR-Q meets the need of high power
broadcasters desiring the azimuth pattern performance of a side-mounted
antenna along with the broadband performance and high power handling of a
panel. This highly engineered antenna has been specifically developed for
multichannel combined applications. We recommend that you consult
Dielectric when considering this antenna. Pattern studies are recommended to
take full advantage of the azimuth pattern offered by this antenna design.
Multi-Station Operation
The wideband characteristics and high power capacity of the DCR-Q make
this antenna an ideal alternative to panel antennas. A variety of custom
options are available.
General Specifications:
Pattern Circularity in Free Space: ± 1 dB
Element Diameter: 45″ (114.3cm)
The Dielectric DCR-Q element is designed with rugged heavy wall brass
tubing. The power dividers and bay feeders are copper and brass construction
all designed for long life and reliability. The DCR-Q is a side firing helix design
consisting of four dipole elements providing true circular polarization.
Ice stability
Due to the broadband nature of the DCR-Q element, it is inherently stable.
Deicers are recommended for applications where heavy icing conditions are
Weight and windload
The relative low weight and windload of this antenna makes it ideal for towers
that could not otherwise support a master FM panel antenna or for applications
where the cost of reinforcing a tower is prohibitive.
Low RF cross section
The low profile of the antenna also makes it an ideal candidate for candelabra
applications. When mounted on a small support structure, it has minimal impact
on other antennas at the same height.
Beam tilt and null fill
Beam tilt and/or null fill are normally included in arrays of eight bays or more,
however, they may also be utilized on smaller arrays. Contact Dielectric and we’ll
design an antenna to meet your specific needs.
