Introduction
The Real Freedom Active UHF Splitter is an optional component to add additional functionality to the Real
Freedom Fiber Antenna Extender system. The splitter provides multiple RF receiving paths allowing up to six
Real Freedom Receivers to be simultaneously supported by a single Real Freedom Fiber Base unit.
NOTE: An alternative option is to use a Real Freedom Fiber Base (Rack Mount), which combines
the fiber base and active splitter in a single unit.
Configuration example
This example shows multiple RF cameras incorporating camera control deployed from a single remote site
utilizing a single SMPTE hybrid fiber cable.
The Real Freedom Fiber Antenna Extender system consists of a Real Freedom Fiber Base unit (IFB-3211)
which integrates with a Real Freedom Receiver for command and control along with a Real Freedom Fiber
Remote unit (IFR-3211). Providing power to remote Real Freedom Downconverters and Data Transmitters
over hybrid fiber cable, the system supports multiple RF cameras.

Installation and configuration
This chapter contains the installation instructions for the Real Freedom Active UHF Splitter.
Overview
The main installation and configuration steps for a Real Freedom Active UHF Splitter are as follows:
1. Optionally, rack mount the UHF splitter in a standard equipment rack.
You can install two UHF spitters side by side in the rack.
2. Connect the RF outputs from a Real Freedom Fiber Base unit to the Real Freedom Active UHF Splitter.
3. Connect the RF outputs from the Real Freedom Active UHF Splitter to Real Freedom Receivers.
4. 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 location for the UHF splitter, you should take note of the following points:
•In general, you should install UHF splitters in an area 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 a UHF splitter close to the receivers, ideally in the same equipment rack, to minimize the loss of
RF signal strength.
•Install a UHF splitter close to the Real Freedom Fiber Base unit to minimize RF cable lengths and the
loss of RF signal strength.
Alternatively, use a Real Freedom Fiber Base (Rack Mount), which is a combined fiber base unit and
active UHF splitter.

Unpack the active splitter
Unpack the Real Freedom Active UHF Splitter 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 Real Freedom Active UHF Splitter for signs of damage. Report any damage to the Real Freedom
Team.
Additional items required for installation
To install the Real Freedom Active UHF Splitter, you will require the following additional items:
•936 V DC power supply with 4-pin LEMO connector.
•Standard 19-inch equipment rack with at least one Rack Unit (RU) of free space and a Real Freedom
UHF Splitter Rack Mount Kit (20006-9-005) if you intend to rack mount the UHF splitter.
•The other components of your Real Freedom installation, which may include one or more receivers,
downconverters, data transmitters, camera back transmitters and cameras, fiber base and remote units.
Cable requirements
To install the Real Freedom Active UHF Splitter, you will require the following cables:
•Coaxial cables with BNC connectors.
It is recommended that you use good quality 75 Ohm cable.
Rack mount a UHF splitter
The Real Freedom Active UHF Splitter is designed to be mounted in a standard 19-inch (48.3 cm) equipment
rack. The unit is 1RU high and half rack width. A rack mount kit (20006-9-005) allows you to mount two UHF
splitters side by side.
NOTE: You can also place a UHF splitter on a solid, stable surface.
Tools
To rack mount a Real Freedom Active UHF Splitter, you will require the following tools:
•#3 Phillips head screwdriver
Precautions
You should read these precautions before you install a Real Freedom Active UHF Splitter in an equipment
rack.
•Active UHF splitters are fragile and vulnerable to damage. If you drop or damage the unit, it should be
returned to BSI for inspection.
•Before you begin the installation, make sure that the splitter is disconnected from the power source.
•Close any open spaces in the rack with blank panels since open spaces will reduce cooling efficiency.

Real Freedom | Active UHF Splitter Product Manual 8 of 16
•To prevent the risk of overheating, use in a well-ventilated area.
•Since there is no power button (on/off switch) on the UHF splitter, ensure that you have access to the
rear of the rack or leave a sufficient wire management loop to pull the unit out from the front of the rack.
Mounting procedure for a UHF splitter
To mount the UHF splitter, you will require 1RU (1 ¾ inches, 44.45 mm) of vertical rack space and a Real
Freedom UHF Splitter Rack Mount Kit (20006-9-005).
1. Attach the Rack Mount Plate to each UHF splitter using four M3 x 8 screws.
2. Install the UHF splitter at the desired location in the equipment rack and secure to the vertical uprights
using four rack screws.
Connections
Refer to the following drawing which shows the locations of the connectors on the Real Freedom Active UHF
Splitter.
CAUTION: To prevent damage, it is recommended that you only use BSI supplied cables and
accessories with this product.
