NGS20-C360-SBL
UHF Broadband Slot Antennas with Enhanced Front to Back Ratio for NextGen Single Frequency Networks. Low Wind-load, Elliptically or Circularly Polarized.
PRODUCT DESCRIPTION
The NGS-SBL (Suppressed Back Lobe) series antennas are ideal for multi-channel Next Generation TV networks. These antennas are designed to reduce radiation in the rear direction to minimize interference to adjacent services. For difficult network planning scenarios, these antennas will enable the network designer to meet the FCC requirements without resorting to large reductions in radiated power.
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 or circular polarization is available for improved transmission to portable and indoor devices.
The NGS-SBL 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
- Reduced rear radiation (suppressed back-lobe design) simplifies network planning for difficult sites reducing the need for large ERP reductions to mitigate interference.
- 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 or circular polarization performance – improves signal penetration and network performance.
- Supplied with brackets for side mounting to a wide range of tower leg sizes.
