The OMNI-291 is another external antenna model made by Poynting.  It's a modified version of the OMNI-69, but with special housing. This model has a 7dBi peak gain across all bands from 450-2700MHz and whhy it’s called “ultra-wide band” antenna. It covers all wireless communication operating frequencies with excellent balanced gain across frequencies. It can cover GSM, 3G, 4G/LTE operating frequencies and can work on all Irish Network Operators, making this model a true high-performance omni-directional external/internal antenna. This model is widely used around the globe and known to improve signal reception in almost everywhere. It is often recommended as marine or coastal antenna by forum members in known South African and European forum sites and discussion boards.

Antenna Performance Plots

Voltage Standing Wave Ratio (VSWR)

VSWR is a measure of how efficiently radio-frequency power is transmitted from a power source, through a transmission line, into a load. In an ideal system, 100% of the energy is transmitted which corresponds to a VSWR of 2.5:1.The OMNI-291 delivers superior performance across all bands with a VSWR of 2.5:1 or better.
