TX RX Systems launches 439 tower top amplifier for 700/800 MHz networks

By AI, Created 3:06 PM UTC, June 03, 2026, /AGP/ – TX RX Systems introduced its 439 Tower Top Amplifier platform on June 3, 2026, targeting 700/800 MHz critical communications sites that need current production hardware, stronger receive performance and easier maintenance planning. The platform is aimed at public safety, utility, transportation, government and other networks with aging infrastructure or planned site refreshes.

Why it matters: - The 439 platform is aimed at agencies and system owners that need current hardware for aging 700/800 MHz sites without adding complexity. - TX RX Systems is positioning the product for maintenance, spares planning, site refreshes and network expansion across critical communications markets. - The platform is designed for receive-path performance in harsh outdoor environments where reliability affects network continuity.

What happened: - TX RX Systems introduced the 439 Tower Top Amplifier platform on June 3, 2026, in Angola, New York. - The product is a current-generation TTA platform for 700/800 MHz communication environments. - The platform is being offered to Land Mobile Radio, public safety, utility, transportation, government, education, industrial and commercial customers.

The details: - The 439 system offers at least 22 dB net gain, a minimum of 110 dB rejection and low-noise performance rated at 2.5 dB max at +25°C and 2.7 dB max at -30°C to +60°C. - The tower top amplifier section provides at least 28 dB of gain and operates over 799 to 816 MHz. - TX RX Systems houses the tower top amplifier in a NEMA 4X aluminum enclosure with epoxy-painted construction. - The platform includes an updated deck interface intended to improve field interaction. - Electronically adjustable attenuation is available in 0.5 dB increments through an LCD touchscreen interface. - Expandable output options let integrators and system managers configure the system for site-specific needs. - The platform is intended for tower top receive amplification, remote site support, donor site applications, multi-site system enhancements, equipment upgrades and other receive-path applications. - TX RX Systems says the platform is a current production solution for applications that previously used earlier TTA configurations. - The company is making the 439 available for quotes, technical guidance and system planning through sales@txrx.com or txrx.com. - TX RX Systems says it continues to manufacture and support RF solutions from its New York facility.

Between the lines: - The launch signals a move from one-for-one replacement thinking toward matching sites with a current platform based on performance requirements and long-term maintenance plans. - TX RX Systems is tying the 439 to a broader RF infrastructure strategy that treats receive amplification, filtering, combining, BDAs, DAS products, monitoring systems and antennas as connected parts of the communication path. - The focus on long-term availability, configuration and technical support suggests the company is targeting buyers who plan infrastructure over multiple years, not just immediate equipment swaps.

What’s next: - TX RX Systems will work directly with customers, engineers, integrators and system operators to review requirements and match the 439 to appropriate applications. - The company expects the platform to support site maintenance, system refresh work, future maintenance standardization and spare equipment planning. - TX RX Systems will continue marketing the product for network upgrades and long-term infrastructure support in critical communications sectors.
