Introduction
The Real Freedom Fiber Antenna Extender provides unparalleled flexibility of operation. Multiple RF
cameras incorporating camera control may be deployed from a single remote site utilizing just a single
SMPTE hybrid fiber cable.
The system consists of a fiber base unit (IFB-3211) which integrates with a Real Freedom Receiver for
command and control along with a fiber remote unit (IFR-3211). Both units are fully weatherproof and are
linked together by a single SMPTE hybrid or single mode dual fiber cable.
The Real Freedom Fiber Antenna Extender incorporates an SDI/ASI return video channel from the base unit
to the remote unit and allows you to simultaneously extend camera control and receive antennas by up to
2 km / 1.5 miles with a single hybrid fiber cable. Providing power to remote Real Freedom Downconverters
and Data Transmitters over hybrid fiber cable, the system supports multiple RF cameras with a single
SMPTE cable.

Installation and configuration
This chapter contains the installation and configuration instructions for the Real Freedom Fiber Antenna
Extender (fiber base and fiber remote units).
Overview
The main installation and configuration steps for a Real Freedom Fiber Antenna Extender are as follows:
1. Optionally, pole mount the base and remote units.
2. Connect a Real Freedom Downconverter to the remote unit.
To remotely control up to six Real Freedom Camera Back Transmitters and to provide camera control of
most brands of broadcast camera, connect a Real Freedom Data Transmitter to one of the
downconverters.
3. Connect the base unit to the remote unit using a fiber cable.
4. Connect the RF outputs from the base unit to a Real Freedom Receiver either directly or via an active
UHF splitter.
5. From the receiver, monitor fiber optic signal levels, voltages, and currents of connected equipment, which
can help to alert you when RF performance is affected. If RF levels are low, use the receiver to
introduces extra gain into the system.
Preparation
When planning the installation locations for the fiber base and remote units, you should take note of the
following points:
•In general, you should install the base and remote units in areas where they can be accessed easily by
support technicians. This area should also be out of reach or inaccessible to anyone that does not need
to gain access, such as fans at a sporting event or attendees at a conference.
•Install the fiber base unit close to the receiver to minimize the loss of RF signal strength.
•Install the antenna close to the downconverter using the shortest cable length as possible to minimize
cable loss.
•Locate the remote unit as close as possible to the downconverter to minimize RF cable loss.

Power requirements
The following table summarizes the power requirements for a Real Freedom Fiber Antenna Extender.
Table 2: Power requirements
Specification
Details
Power
936 V DC
Consumption
Each fiber unit consumes about 8.5 W. Note this does not include
any peripherals connected to the remote unit such as a
downconverter and data transmitter.
The recommended power supply for a SMPTE fiber base unit is
Mean-Well GST90A24-P1M (24 V 90 W). This provides sufficient
power for a fiber base and fiber remote with two downconverters
and a data transmitter connected.
Note that the remote unit requires a power supply for fiber lengths of greater than two kilometers.
When using SMPTE, the remote unit does not need power unless the fiber length exceeds two kilometers. If
you are using other fiber connectors, for example, ST or LC, then these do not include a means for power
insertion over the fiber and the remote unit must be powered locally.
Unpack the fiber antenna extender
Unpack the Real Freedom Fiber Antenna Extender and refer to the packing list to ensure that all items are
included. Report any missing items immediately to the Real Freedom Team.
Inspect the base and remote units for signs of damage. Report any damage to the Real Freedom Team.
