The document provides photographs and diagrams showing applications and uses of the Sagittar MN Series Radios. The radios can be used to transmit data from IP cameras over wireless links using external antennas. They also allow power to be fed through the radio directly to an IP camera. The radios can operate in access point mode, where the base station radio sets the frequency, or bridge mode, where all radios must have their frequencies set individually.

Photographs of the Sagittar MN Series Radios
“MIMO 802.11n Radios”
The photographs and graphics below are intended to provide an introduction to
the MN Series Radios and a background on applications and uses e.g. sending
data from IP Cameras over radio links.
Notes on the above photographs:
1. Top Left: Shows a bracket for the MN radios (pole diameter <50mm)
2. Bottom Left: There is a removable panel at the bottom of the MN Radio. You remove the
panel to access the radio’s connectors.
3. Top Right: It is possible to feed power through the MN Radio, directly to an IP Camera.
4. Bottom Right: If you are going to connect to an external MIMO antenna, make sure to use
Reverse-SMA connectors.

2. MN-Series Radio Applications - Photographic Introduction
The diagram below shows how the “client” radios connect directly to IP Cameras.
You can use an external MIMO Parabolic antenna to increase distance of a radio link and reduce the
chances of interference (use of higher-gain, larger-sized antennas makes sure there is higher received
power which helps when interference is a concern. Also, higher-gain, larger-sized antennas have a
narrower beamwidth, which helps reduce a radio’s susceptibility to interference). In the diagram below,
on the right, you can see how the “Base Station” radio can also be connected to an external Sector
antenna (examples of MIMO Sector antenna beamwidths are 90Degrees and 65 Degrees).
In the example below, power to the IP Camera is fed from a +15VDC supply, through a PoE (Power-over-
Ethernet) injector and the Sagittar MN-Series Radio.

The diagram below shows how the “client” radios connect to IP Cameras.
In the diagram, on the right, you can see how the “Base Station” radio in optionally connected to an
external Sector antenna (examples of MIMO Sector antennas beamwidths are 90Degrees and 65
Degrees).
In the example below, power to the IP Camera is fed from a +12V battery through a PoE injector to the
Sagittar MN-Series Radio. In the diagram below, power supply to the IP Camera is from a battery.

“AP” to “Client” Mode
The diagram below shows how the “client” radios connect to a “Base Station”, which is an MN Radio
working in “AP Mode” (Access Point Mode). The frequency is set in the “Base Station” radio that is
configured to work in AP Mode. When the frequency of the AP is changed by the user, the Client
Radios will all automatically “follow” the frequency of the AP. The radio’s “half power” beamwidth
is 35 degrees for azimuth (i.e. horizontal) and 15 degrees for elevation (i.e. vertical).

“Bridge” Connection Mode
The diagram below shows how the “client” radios connect to a “Base Station” using Bridging Mode.
The frequency is set in the Clients AND in the “Base Station Radio”. You establish radio link
connections by entering the MAC address of the “remote radio” within the “local radio” (and you
enter the MAC address of the “local radio” within the “remote radio”). To change frequencies of all
connected radios, you must change the frequency settings in ALL bridged Radios.
