Product Description

Griddy is an ultra wideband parabolic grid antenna that’s ready to help you get the most out of your LTE modem, booster, or WiFi device!

Have line of sight to your nearest cell tower or a distant WiFi access point? Great! Simply aim Griddy in that exact direction, and you’re all set!

High Gain and Highly Directional

Griddy adds up to 26 dBi of gain to your wireless connection, making weak signals considerably stronger and clearer

  • 12-17 dBi at 600-960 MHz
  • 20-23 dBi at 1700-2700 MHz 
  • 23-26 dBi at 3000-6500 MHz 

You need line of sight to the cell tower or WiFi access point for Griddy to work well. Griddy’s super high gain means that any signal dispersion or reflection from trees or buildings will make Griddy much less effective.

Installing Griddy

As long as you’re handy, professional installation isn’t required. This antenna isn’t any more involved than any other kind of rooftop antenna to mount, but will take a bit of careful aiming to get dialed in.

We cannot state this enough, Griddy has a very, very narrow beam width. It only “sees” a very narrow horizontal and vertical aperture. To get the best results, you’ll want to move slowly to find the exact right direction. Even a 1-2 degree variance can make a huge difference.

Installation requires two 10mm wrench, socket or nutdrivers, or alternatively an adjustable wrench and/or pliers.

Griddy has N-Female connectors, measures 24 x 39 x 16 inches and is made of ASA anti-UV and aluminum. It is IPX weather rated and rated to a wind velocity of 130 mph.
