The APT series antenna is a versatile, dual-input broadband panel system for UHF high-power, multi-channel variable vertical polarization operation

RAYMOND, Maine – April 18, 2017Dielectric, a pioneer in purpose-engineered antennas and RF systems for TV and radio broadcasters, announces that its broadband, high-power APT Panel Antenna will debut at the 2017 NAB Show, taking place April 24-27, in Las Vegas. Dielectric exhibits at Booth C2613.

The APT Panel Antenna is one of three new Dielectric antennas designed with the Spectrum Repack in mind, including the TFU-GTH-BB high-power broadband pylon antenna announced earlier this month. Dielectric designed the APT Panel Antenna to satisfy broadcasters that prefer panel-type antennas with the capability of adjustable vertical polarization. Like the TFU-GTH-BB broadband pylon antenna, the APT Panel Antenna also features Dielectric’s exclusive, built-in FutureFill technology, which makes it ATSC 3.0-ready.

“With these two new products, Dielectric now offers best-in-class high-power broadband antennas—in both a pylon and panel antenna style—as part of its broad portfolio of RF transmission products,” said John Schadler, vice president of engineering for Dielectric.

The APT Panel Antenna’s broadband capabilities will support more than one station, providing ideal flexibility for use in channel-sharing scenarios coming out of the Spectrum Repack. Additional flexibility is provided by enabling each station to operate with independent horizontal/vertical ratios.

With removable radomes and breakaway panels, Dielectric’s APT Panel Antenna improves maintainability through access to the internal feed system.

FutureFill, also new for NAB, will help broadcasters boost signal strength so that the APT Panel Antenna can heavily saturate the coverage area more cost-effectively than by increasing the transmitter size or power level. This is especially important upon transitioning to ATSC 3.0, which will require higher signal strengths to provide greater channel capacity to deliver an improved quality of service – along with robust delivery of new services anticipated through the IP-native architecture of ATSC 3.0, including mobile DTV and media streaming.

Based on OFDM carrier technology and the subsequent higher peak to average power ratios associated with ATSC 3.0, Schadler adds that the APT panel antenna incorporates higher voltage safety factor considerations that were carefully engineered in Dielectric’s Raymond, Maine manufacturing facility.

“The antenna employs a fully coaxial feed system that is pressurized to the feed point,” Schadler said. “By not using any stripline or microstrip technology, the voltage safety factors are greatly increased making the antenna ready for ATSC 3.0 operation.”
