The FM rollout includes the first installation of a Flexiva FLX liquid-cooled transmitter in Brazil
GatesAir has partnered with Foccus Digital in Brazil to upgrade Sistema Clube’s over-the-air broadcast infrastructure in the greater Sao Paolo region. Using GatesAir liquid and air-cooled transmitters to power single-frequency networks, the project upgrades existing ISDB-Tb digital TV infrastructure and expands FM coverage, improving signal quality and integrity across nearly 200 square miles.
The FM rollout comprises two new sites powered by Flexiva™ FM transmitters, including the first installation of a Flexiva FLX liquid-cooled transmitter in Brazil; and one Flexiva FAX air-cooled transmitter. GatesAir Intraplex® SynchroCast® technology seamlessly networks FM content across multiple transmission sites over IP, ensuring all transmitters deliver program content to their specific coverage areas in lockstep.
The TV project replaces existing transmitters with 13 Maxiva™ high-efficiency UHF transmitters—a mix of ULXTE liquid-cooled and UAXTE air-cooled models—which integrate GatesAir’s Maxiva XTE exciter. The XTE’s advanced signal processing power and real-time adaptive correction software delivers a more robust signal to strengthen signal quality and integrity across the entire coverage area, which spans from congested urban neighborhoods to rural and coastal regions.
Robert Houghtaling, business development manager for Foccus Digital, says: “The tropical climate of the Sao Paolo region means makes the reduction of air conditioning loads and energy consumption in the RF plant a high priority. GatesAir’s liquid-cooled architecture cleanly transfers heat from inside the plant to the outside, which substantially lowers cooling and electricity costs for Sistema Clube. The modular design of all GatesAir transmitters also brings efficiency gains through simplicity of installation and ongoing maintenance, the latter of which amounts to long-term monetary savings tied to reduced labor and spare parts management.”
Specific to maintenance, Maxiva and Flexiva transmitters adopt a similar modular architecture that allows engineers to replace power amplifier modules and power supplies while remaining on the air.
“The unique characteristics of single-frequency network architectures requires a careful balance of network planning and technical implementation to ensure exceptional performance across multiple sites tied to signal integrity and synchronous delivery,” explains Bruce Swail, CEO, Gates Air. “Working closely with our Brazilian partner Foccus Digital, these upgrades ensure that Sistema Clube has the latest available technologies to at once improve quality and coverage for local audiences while lowering total cost of ownership across their TV and radio infrastructure.”
