airMAX® Carrier Class 2x2 PtP Bridge Dish Antenna
Model: RD-5G31-AC
High Isolation and F/B Ratio
Ruggedized Mounting
Protective Radome Included

Overview
Datasheet
The RocketDish RD-5G31-AC is a
Carrier Class 2x2 Bridge Dish Antenna
that was designed to seamlessly
integrate with RocketM radios
(RocketM sold separately).
Pair the RocketM’s radio with the
RocketDish antenna’s reach to create
the endpoint of a high-performance,
Point-to-Point (PtP) backhaul. On
the right is one example of how the
RocketDish can be deployed.
Superior Performance
The Ubiquiti Research and
Development team engineered the
RocketDish RD-5G31-AC with high
isolation and Front-to-Back (F/B) ratio.
The main benet is improved
Signal-to-Noise Ratio (S/N or SNR).
The improved F/B ratio and lower
sidelobes reduce the interference
from other transmitters in the
area–potentially on the same tower.
The improved S/N ratio allows a
higher-order modulation to be used,
for example, 256QAM rather than
16QAM. This in turn increases the
number of bits per second for a xed
bandwidth, which is also known as the
data rate.

Because of its advanced engineering,
the RocketDish RD-5G31-AC provides:
• Enhanced co-location
• Better performance
• Additional range
airMAX Technology*
Unlike standard Wi-Fi protocol,
Ubiquiti’s Time Division Multiple
Access (TDMA) airMAX protocol
allows each client to send and receive
data using pre-designated time
slots scheduled by an intelligent AP
controller.
This “time slot” method eliminates
hidden node collisions and maximizes
airtime efciency. It provides
many magnitudes of performance
improvements in latency, throughput,
and scalability compared to all other
outdoor systems in its class.
Intelligent QoS Priority is given to
voice/video for seamless streaming.
Scalability High capacity and
scalability.

RocketDish antennas and RocketM radios have been designed to
seamlessly work together. No special tools are required – simply snap
the RocketM into place using the built-in, universal Rocket mount.
