RFI CDR2795-ISM900 collinear antenna

RFI’s ISM 6 dBi collinear antenna delivers high gain and optimised operation through advanced construction methods and band-specific tuning. It is a high-performance choice for IoT gateways and standalone base devices where isolation or distance requires best-in-class antenna optimisation.

The CDR2795-ISM900 is tuned specifically to the ISM 900 MHz band, providing good radiation pattern performance and signal efficiency. Unlike wideband antennas that must compromise across a broad frequency range, its narrowband design focuses energy precisely where it is needed, achieving 6 dBi of usable gain.

This increased gain enhances system efficiency, improving signal strength and stability even under low-power conditions. In situations where every decibel counts, the product provides maximum power transfer and consistent radiation patterns.

Central to the antenna’s performance is RFI’s Meander Flexible PCB construction, a precision-engineered solution that combines electrical consistency, mechanical strength and long-term performance. Key advantages include: optimised impedance control for reduced signal loss and high efficiency; enhanced mechanical durability to withstand vibration and environmental stress; and consistent manufacturing repeatability for dependable field performance.

With versatile mounting options — including spring or bulkhead configurations — the antenna can be used across a variety of deployment scenarios, including vehicle and bracket mounting.
