OMNI-297 Poynting Antenna.

Overview

The Poynting OMNI-297 is a 2dB omni-directional 4G/5G LTE wideband antenna, designed to focus on superior pattern control for reliable, consistent performance across the entire frequency range. This antenna is designed to be extremely robust and capable of withstanding extreme conditions, evidenced by its IP 69K rating, making it ideal for marine environments. It's very versatile in its installation options, coming with mounting equipment for pole, wall and flat surface mounting.

The OMNI-297 is a SISO antenna, ideal for equipment such as routers and IOT gateways which use a single LTE input, and also features 2.4GHz WiFi facilities, meaning it can be used for broadcasting or receiving WiFi signals as well as its standard use of boosting the 4G/5G LTE signal. It covers all current 4G signal bands and is futureproofed for all future 5G bands too.

This antenna comes with a 60 centimetre cable terminated with an SMA plug connector. It's lightweight, sleek design makes it easy to install.

Guest Article - Choosing between a directional or an omni antenna, by  Stephen Froneman of Poynting

Article - Poynting: Choosing between a directional or an omni antenna, by Stephen Froneman of Poynting

The choice of omni-directional and directional antenna is not always simple. We will explain the key differences experienced by using a uni-directional (aka ‘directional’) antenna vs. an omni-directional (aka ‘omni’) antenna.

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.
