Oscar 405G / 4G, Dual Band Wi-Fi and ISM Omnidirectional Wall/Pole Mount Antenna

The Oscar 40 is a compact omnidirectional antenna designed to support a wide range of modern wireless communication standards across cellular, Wi-Fi, and ISM frequency bands. It provides reliable performance for 5G NR, 4G LTE, legacy cellular technologies, dual band Wi-Fi, and low power IoT networks, making it suitable for diverse connectivity requirements in commercial, industrial, and public network deployments.

Engineered for outdoor operation, the antenna features a UV protected and water resistant radome that ensures long term environmental durability. Its compact form factor makes it well suited to discreet installations where space, visual impact, or mounting constraints are a concern, while still delivering performance that exceeds many larger omnidirectional antenna designs.

The Oscar 40 is supplied with an aluminium mounting bracket for wall installation and includes a mast clamp for pole mounting, providing flexible installation options. It is delivered as standard with an SMA male connector and a choice of 5 m or 10 m low loss cable. Alternative connector types and custom cable lengths are available on request for volume orders.

This antenna is well suited to applications such as cellular connectivity, public wireless systems, IoT networks, Wi-Fi bridging, smart agriculture, and industrial telemetry. Its broad frequency coverage and ground plane independent design make it an effective solution for both fixed infrastructure and remote deployments worldwide.

Spectral Frequency Diagram

The Spectral View Diagram visually describes the performance of the antenna from 400 MHz to 6000 MHz. Key frequencies are marked highlighting the technology used and the colour represents the performance at that frequency taking in to consideration the VSWR and radiated efficiency of the antenna.

Green is considered a suitable band, amber is adequate in good signal conditions and red is likely to be unsuitable.
