YAGI antennas for New York City Subway
HUBER+SUHNER supplies trackside and on-board antennas to Thales Canada Transportation Solutions, supporting the New York City Subway CBTC system.
HUBER+SUHNER has been chosen to supply Thales with a range of trackside and on-board antennas and cables to support the CBTC (Communications Based Train Control) system on the New York City Subway. CBTC enables continuous, high capacity, two-way digital communication between each train and control centre. The control system benefits from enhanced information such as train performance data and continuous determination of train location and speed.
Under a contract with Thales Canada Transportation Solutions, SENCITY® SPOT-M Yagi antennas, rolling stock SPOT-S antennas, together with radio frequency (RF) cable assemblies, all supplied by HUBER+SUHNER, will be used to provide the train-to-track radio network for trackside and rolling stock on the New York City Transit Flushing Line 7.
The Yagi antenna was chosen because a higher-gain antenna gives improved radio frequency coverage and therefore achieves better network reliability. It is also the ideal shape and design for tunnel installations, including between narrow tracks, since space is always an issue in such environments. The construction of the antenna protects it against water penetration and moisture, further optimizing its performance.
Scott Annis, Sales Director North America of HUBER+SUHNER said: “Thales Canada had a requirement for a high performance, narrow beam trackside antenna for use in the many tunnels that the New York City Subway trains travel through and our Yagi antenna fulfilled that need.”
He continued “Thales is a long-term partner of ours and we already supply the company with antennas, low frequency and radio frequency cables, and soon, fiber optic products”, so it is likely that HUBER+SUHNER will deliver more antennas and other products, worldwide, in collaboration with Thales.
