## Description

Say hello to Griddy! 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! Griddy adds up to 26 dBi of gain to your wireless connection, making weak signals considerably stronger and clearer. You need line of sight to the WiFi access point or cell tower 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. 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. Our dedicated Waveform support team is ready and eager to help you get Griddy installed. Whether it’s a weekday or weekend, send us a text message or give us a call!

Review: Works great for distance. Went from 0 to 1 bar, 18 miles from tower - Worked great in rural AK. Used “Cell Antenna” app to locate closest tower (18 miles away). Then used “Coordinates” app to get exact direction (degrees). When we headed to the cabin- no reception), used iPhone compass to match the predetermined degrees. Placed on highest spot on cabin: still has trees and hillside blocking direct sight - no chance of actually seeing the tower. The antenna has a very small window of degrees to catch the signal from that distance (10 degrees max). Connected the cable to a mifi hotspot with hotspot SIM card (https://www.desertcart.com/gp/aw/d/B08F2WW1H1?psc=1&ref=ppx_pop_mob_b_asin_image ) and 10k battery pack- and went from nothing to being able to text, basic surfing (desertcart shopping) and 90% clear phone calls. Very happy - 250$ or so for a complete setup and 30$/month for hotspot service.
Review: Quality product - 5* because assembly was easy/good instructions, hardware is high quality / fasteners are stainless steel, good quality on cable and adapters also. I’ll share that with this product I also had a learning experience on cell towers. I live on a bluff and have direct line of sight to 20+ cell towers, 8 of these are within the 10 mi radius required by this antenna. I thought that I would surely see the 100+ mbps shown on youtube by pointing a yagi antenna to the closest tower (4mi). I was wrong… Most of the towers that i can see follow a road, and i later learned they only broadcast signal along the road… not in the direction of my house. I found that only one of the 20+ towers was sending signal in the direction of my home. I recommend googling and finding a cellmapper tower site that shows the direction of the tower signal. Additionally, I think the secret is out on cell internet in rural areas. After installation, m the best mbps I’ve experienced was 44 mbps. But most often my connection is between 2 - 14 mbps. I can definitely see the connection speed is effected by peak hours; days and evenings are slower and late nights and mornings are much faster speeds. My provider is not throttled.

## Features

- SAY HELLO TO GRIDDY! - Ultra-wideband yet super high gain. Griddy has 12-17 dBi of gain on the 600-960 MHz frequency bands; 20-23 dBi of gain on the 1700-2700 MHz frequency bands; and 23-26 dBi of gain on 3000-6500 MHz frequency bands.
- GRIDDY NEEDS LINE OF SIGHT - Since Griddy has such high gain, it’s important to have line of sight to the cell tower or WiFi access point you’re connecting to. Any dispersion or reflection through trees or buildings will make Griddy much less effective.
- LIGHTNING FAST DATA RATES: Struggling to get a consistent signal with a cell booster? Getting low data rates from your LTE modem? As long as you have line of sight to the tower, Griddy will help you get blazing fast data. Simply install the antenna in place of your current antenna, aim it at the tower, and enjoy the fastest possible data rates.
- GRIDDY SUPPORTS 4G LTE, 5G NR, and WIFI: Griddy connects to the antenna ports on your hotspot, router, or WiFi device to give you extra signal. Griddy comes with 50 Ohm N-Type connectors, as well as TS9 and SMA adapters. You’ll need to connect this antenna to a signal booster, LTE router, or WiFI access point.
- USE 2X OR 4X GRIDDY KITS FOR MIMO: If your WiFi/LTE/5G device supports multiple external antennas you can choose to use just one Griddy or buy multiples to get all the benefits of MIMO.

## Questions & Answers

**Q: Does this use mimo?**
A: you'll need to purchase two Griddy antennas, and mount them in a cross polarized pattern in order to achieve a MIMO configuration. If you need information on how to configure the antennas please reach out via text to 949-449-2290 and we'll help best we can!

**Q: What brackets are needed to mount 2 of these antennas at 45°and 135°?**
A: this antenna is made for only 90 deg installation. if you need to go at 45 deg best is to use a sure call antenna that is set up for those angles. the sure call yagis are just at powerful. this parabolic is a line of sight monster but anything else is a waste of time. i have both the parabolic for cellular booster. and the Yagis for dual hotspot reception like the netgear m2, m5, m6.

**Q: Soy de El Salvador, podría funcionarme esta antena?**
A: Hola, la antenna funciona con cualquier frecuencia entre 600-6500Mhz. La mayoría de operadores a nivel mundial se encuentran en esas frecuencias. Te sugerimos revisar que frecuencia y banda utiliza tu operador local en El Salvador para asegurarte de tu compra. En caso de necesitar mas ayuda, puedes contactarnos en waveformDOTcom

**Q: Me puede funcionar en Honduras esta antena?**
A: Hola Sergio! Sí. Las antenas son componentes pasivos, entonces sirven para cualquier banda celular que esté entre la frecuencia del rango (600-6500 MHz). Nuestros productos suelen estar optimizados para las bandas estadounidenses (el mayor gain sucede en esas bandas), pero igual va a funcionar con otras bandas dentro del rango.

### ⭐⭐⭐⭐ Satisfied
*by D***. on August 28, 2023*

I’ll admit I was not expecting this to actually work, but I will say I’m impressed. It is working a lot better than I expected. My only issue was that I wished it came with longer cable or at least made it to where someone can list the length of cable availability. Also need to clarify what type of booster that this can hook up to without accessories needed
