OMNI-280 Poynting Antenna.

Overview

The Poynting OMNI-280 is a versatile omni-directional antenna designed to support a broad range of mobile and wireless applications by covering wide frequency bands and offering flexible mounting options. With its wideband design, the OMNI-280 spans Mobile frequencies from 617MHz to 4200 MHz, making it suitable for 2G, 3G, 4G/LTE &5G usage.

One of the distinguishing features of the OMNI-280 is its mounting flexibility. The antenna can be pole-mounted, wall-mounted, or surface-mounted, making it suitable for a broad range of environments.
From outdoor fixed installations, machine-to-machine or IoT setups, to indoor deployments where space or mounting possibilities may be constrained. The OMNI-280 is rated to IP65, meaning it is designed to withstand outdoor weather conditions such as wind and rain, which further reinforces its suitability for both indoor and outdoor use.

The OMNI-280 is ideal for applications such as water/electric meters, retail or point-of-sale devices, security equipment, M2M applications (telematics), and other industrial setups where space, cost, and installation simplicity are considerations.

Its design balances moderate gain with wideband coverage and robust mechanical characteristics, offering a compelling option when you need dependable connectivity without complicating the installation with alignment challenges or heavy hardware.

Overall, the OMNI-280 offers an accessible, future-proof antenna solution for wide-band mobile connectivity, especially where installation flexibility and rugged outdoor performance matter more than maximum gain or ultra-high performance deployment.

Article - IP Ratings Explained, by  Daniel Coombs

Article: IP Ratings Explained

IP ratings, or Ingress Protection ratings, are a standardised benchmark of how capable a product is of withstanding ingress from foreign entities that could negatively impact its functionality. They’re helpful because terms like ‘weatherproof’ and ‘waterproof’ are unspecific terms and don’t always convey the necessary level of detail.
