ANT-OMNI-291

OMNI-291 Poynting Antenna.

Overview

The OMNI-291 is a unique new design with improved electrical performance and using a standard 1 inch marine mount. The ultra-wide band covers all contemporary LTE operating frequencies with excellent balanced gain across all frequencies. Higher frequencies are not compromised and the antenna design allows Poynting to have superior pattern control over the entire frequency range making the OMNI-291 a true high performance omni-directional antenna.

Usable in all parts of the world, the OMNI-291 guarantees signal reception almost everywhere. Poynting Antennas achieves this through new antenna configuration using multiple dipoles and a unique (patented) feed network. The antenna is future proof as it covers the 450 MHz LTE frequency which is proving to be more and more popular!

See antenna mounting brackets in the accessories tab.

(for normal 4G (LTE) you will need TWO of these antenna)

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.
