RAYMOND, Maine -- April 14, 2008 -- Dielectric Communications, a division of SPX and a leader in broadcast antenna systems, today announced the introduction of two new antennas. The company‘s new DeltaVee and TUM panel antennas provide greater flexibility for broadcasters looking to expand into mobile media transmissions or broaden the functionality of their existing installations.
“Broadcasters are continuing to face new challenges as the broadcasting transmission mediums shift, first from analog to digital and, more recently, the growing prevalence of mobile media broadcasting,” said Dielectric President Garrett VanAtta. “We are excited to introduce the DeltaVee and TUM antennas as a means to provide added flexibility for broadcasters who want to expand the capabilities of their existing antenna arrays, or for those who are developing new transmission sites that are optimized to the demands of both mobile media broadcasting and DTV.”
Dielectric‘s DeltaVee UHF panel antenna is suitable for stand-alone use or can be installed as a part of an existing antenna array. As a vertically polarized antenna, the DeltaVee is an excellent complement to horizontally polarized DTV systems already in place. The new antenna combines the reliability and features of Dielectric‘s proven Deltawing design with all of the advantages of vertical polarization. The DeltaVee offers high-power handling with broadband operation from 470 MHz to 698 MHz and a typical VSWR of less than 1.1:1. Constructed from all stainless steel, copper, and brass, the DeltaVee provides a rugged design for a long life. The antenna is optimized for operation even under the most severe environmental conditions, including heavy ice loading and high winds.
The new TUM panel is a high-power broadband antenna with a variable polarization ratio for maximum flexibility -- from elliptical polarization to full circular polarization. This flexible design allows for a wide range of omni or directional pattern options as well as unique elevation pattern requirements such as beam tilt and null fill. The polarization ratio is controlled by varying the phase relationship, a technique that eliminates the need for unequal power dividers and maximizes the overall power rating of the panel by always applying uniform power to the radiating elements. The antenna features a single-input design that reduces feed system complexity by eliminating unnecessary connections and thus increases system reliability. The TUM antenna provides 200MHz bandwidth, with a VSWR less than 1.1:1, and a power rating of 2 kW per panel.
