NAB Show 2023
Dielectric has evolved its pylon designs to enable secure top-mounted configurations for UHF TV broadcasters. The manufacturer will introduce its first top-mounted, free-standing UHF broadband pylon antenna next week at the NAB Show 2023. Dielectric exhibits at Booth W3601 at the Las Vegas Convention Center through this Wednesday, April 19.
Broadband pylon antennas bring exceptional bandwidth, performance and pattern flexibility to broadcasters, says Dielectric. They have traditionally been offered as side-mounted solutions due to structural hindrances that compromise the pylon from being self-supporting. New for NAB, Dielectric has engineered a structurally-sound, broadband pylon design for top-mounted configurations without sacrificing horizontal and vertical pattern circularity, bandwidth characteristics, and elevation pattern gain.
The new slotted coaxial design supports up to 10 UHF channels while reducing wind load and footprint on broadcast towers.
“Broadband panel antenna systems require higher part counts, external feedlines, and more connection points for installation than pylon systems,” said Dielectric President/General Manager Keith Pelletier. “That complexity increases wind load and reduces system reliability, which increases field maintenance and repairs. Our new generation of UHF broadband pylon antennas enable the coveted top-position on the tower and ensure excellent circularity, made possible by utilizing multiple techniques developed over the past few decades by Dielectric’s engineering team.”
In addition to high-power panel replacement opportunities, Pelletier sees strong opportunity for NextGen TV deployments over the coming several years. “These are attractive designs for higher power applications with multiple stations, and will typically accommodate input power ratings of 60 to 120 kilowatts,” he said. “That makes it perfect as the main antenna for an ATSC 3.0 SFN network, and is otherwise an ideal replacement choice for panel antennas in the field that are nearing end of life, or have become increasingly expensive to maintain.”
