Conventional, Smart or Scalable. Monitoring built around your needs! ITS150A is a rugged RF monitoring sensor designed for mission-critical environments where performance, security, and reliability are essential.
It delivers continuous, real-time VSWR monitoring using hardware-based fault detection—eliminating inaccuracies associated with legacy analog sensors and removing the need for voltage scaling or external controllers. Internal RF logic compares forward and reflected power and triggers latching alarms at predefined thresholds via two independent dry contact relays, ensuring seamless integration with digital telemetry systems.
Fully sealed and configuration-free, the ITS150A features no IP stack, USB, GUI, or network interfaces, providing a zero-attack-surface design aligned with NIST and IEC 62443 cybersecurity best practices. Built with low-PIM, high-quality RF components and durable 3.4-10 connectors, it offers predictable, certifiable performance for public safety, defense, and critical communications applications.
The TJ231(x)B-(y) Series is a high-performance VHF cavity-ferrite transmitter combiner designed for 132-174 MHz
systems, available in 2 to 5 channel configurations as a standalone. Additional options are available when used in system designs. It incorporates low-loss triple-stage isolators and high-Q 1/4
wave bandpass cavity filters, enabling minimum Tx-Tx spacings of 150 kHz. With its 19-inch rack-mountable
design, the TJ231(x)B-(y) Series ensures efficient frequency management and superior isolation, making it wellsuited for aviation, low-band, and VHF applications.
The SC201, SC213, and SC2340 are a rugged family of omnidirectional antennas engineered for reliable VHF and multi-band LMR performance in demanding environments. Designed for aviation, public safety, and land mobile radio applications, the series spans solutions from wideband, low-profile VHF coverage with the SC201, to higher-gain VHF performance with the SC213, and ultra-wideband tri-band coverage with the SC2340 supporting VHF, UHF, and 700/800/900 MHz systems. Built with high-quality materials, fiberglass radomes, and integrated mounting hardware, all SC collinear antennas deliver consistent radiation patterns, low wind loading, and long-term durability in extreme wind, ice, and corrosive conditions—making them a trusted choice for critical communications infrastructure.
The SI500A DAS antenna series is a compact and unobtrusive solution designed for boosting wireless coverage
within buildings. Operating over an ultra-wide frequency range of 617 MHz to 8500 MHz, it supports a multitude
of wireless communications, including 5G networks, legacy systems, Wi-Fi 6E & 7, future 5G bands, and IoT
systems, ensuring uninterrupted indoor connectivity.
