RAYMOND, Maine�Antenna and transmission support equipment maker Dielectric is seeking to please both low-power and high-power radio broadcasters with new offerings for the 2016 NAB Show.

The DCR-U (shown) is aimed at the higher power broadcasters, while the DCP-K is intended for the lower power range.

The company says, �The DCR-U is a broadband, circularly polarized ring antenna that minimizes tower footprint while doubling capacity. Its full bandwidth and high-power design characteristics � notably a pressurized tap point and four-inch balun � support capacity and high-voltage requirements for multi-station operations. The high-voltage protections are especially important for handling the immense voltage peaks that come with passing multiple analog FM and/or HD Radio stations through the same antenna.�

The DCP-K is a broadband, circularly polarized panel antenna. It �reduces the number of cables required in the feed system by half. Instead of using the traditional hybrid feed system and dual-input panels, the DCP-K design incorporates a single input directly into the balun � thus reducing feed line count and connections, which equates to increased reliability.� The company adds, �The DCP-K antenna�s compact and unobtrusive design provides a significant cost benefit to the low-power FM broadcaster, both upon installation and well into the future.�

In addition, Dielectric says it will be an �innovative field-tunable, FM two-channel combiner that eliminates various traditional components from the design. This includes the absence of coaxial Tee junctions, as well as the associated coaxial line and elbows.�

Dielectric Senior Engineer Derek Small said, �Traditionally, a Tee junction, a pair of delay lines and filters are used to multiplex two channels. By removing the Tee and delay lines, we�ve reduced the combiner footprint for space-limited sites and improved efficiency.� He added, �The tunable common case design also protects the broadcaster�s investment in the event of a frequency change, allowing the station to use the same infrastructure instead of replacing filters and line.�
