20dbi - Parabolic Grid Antenna for
  4G-LTE 1800 MHz
- Mobile Broadband

NOTE !!  4G LTE 1800MHz only - NOT suitable for 3G or nextG 


Benefits - Who uses these antennas.

  • USB 4G Routers, Modems and Mobile Phones.
  • GSM services on 1800MHz
  • For Fixed Wireless, Outdoor and Semi-Mobile installs.
  • Suitable for both 4G LTE-FDD 1800 as used by Vodafone Telstra and Optus.
  • Homes, Offices, Mines, Dongas and Geo-technical contractors, but rural and metropolitan.
  • Farms and Stations too far from Mobile phone towers.
  • Correctly installed, this antenna may turn an unreliable 4G internet connection into a fast broadband and quality VoIP service. 
  • Greatly Improves 4G Wireless Internet and Mobile Phone service in rural and marginal signal areas.
This antenna suits 4G LTE services on 1800MHz. At this frequency, like the 2100 GSM/3G band, much signal can be absorbed by rain, fog, and vegetation that is in the direct line from the tower to your location. Also, the signal path needs to be line-of-sight. This doesn't mean you need to be able to see the cell tower, it just means there must be no significant buildings, hills or mountains blocking the direct path.  To get the best LTE connectivity you'll benefit form the greatly increased Signal Strength and Signal-to-Noise ratio these directional antennas will provide.
