NGS-C210C Series
Broadband Slot Antennas for NextGen-TV Networks, Cardioid C210C Azimuth Pattern, Low Wind-load, Elliptically Polarized, High & Low Power versions

Rev : 01 | Rev date : 14 Jan 2021

PRODUCT DESCRIPTION

The NG series antennas are ideal for multi-channel Next Generation TV networks. These antennas are typically deployed at SFN sites that surround the main transmission site in a NextGen-TV single frequency network (SFN). The high-power rating and broadband performance allow multiple channels to be transmitted from an SFN site, thus reducing capital costs and providing consistent coverage across channels. Elliptical polarization is available for improved transmission to portable and indoor devices. The NG family of antennas provide both top mounted and side mounted solutions in a low wind load format.


A wide range of radiation patterns are available. The RFS Antenna Selection Tool contains pattern data for all NGS antenna models and works alongside modern SFN planning tools to help you choose the right NextGen antenna for each SFN site. To download, click Here

FEATURES / BENEFITS

  • Broadband performance for multi-channel SFN networks allows SFN infrastructure sharing and reduces overall CAPEX.
  • Low wind-load reduces tower loads thus simplifying SFN site acquisition.
  • Large range of azimuth radiation patterns – simplifies the SFN planning process to provide optimum network coverage.
  • Broadband elliptical polarization performance – improves signal penetration and network performance.
  • Radiation patterns with reduced back-radiation are available for SFN sites requiring interference mitigation.
  • Supplied with brackets for side mounting to a wide range of tower leg sizes
