A-OMNI-403

OMNI-403 Poynting Antenna.

Overview

The  OMNI-403  is  a  wide  band  LTE  antenna  with  a  smaller  profile  radome  which  is  specifically  designed  for  adverse  marine  &  coastal environments. This antenna uses a standard 1-inch (14 TPI) marine mount for simplified installation to most standard marine attachments. The antenna is designed for superior pattern control over the entire frequency range, making the OMNI-403 an exceptional omni-directional antenna for its size and application. Poynting Antennas achieves this through a new antenna design using multiple dipoles and a unique (patented)  feed  network.  This  antenna  covers  all  contemporary  LTE  operating  frequencies  with  excellently  balanced  gain  across  all frequencies, enhancing LTE performance features, such a multi carrier aggregation (CA). This antenna is suitable on all 5G networks up to 2700 MHz.

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.
