Dual-mode 4-way UHF amplifier Instruction Manual
PROAMP104X
www.blake-uk.com/104x
The versatile amplifier is an addition to the PROception range of UHF multi-way distribution amplifiers.
The unit has two modes of operation, allowing it to be used either as a straight forward multi-way
aerial amplifier for off-air signal distribution, or as a return path amplifier for distribution of the UHF
loop-through output of a Sky* receiver. In the latter mode full support is provided for remote infrared
receivers ( eyes ). The use of F connectors makes the amplifier easy to use and helps to ensure good
system screening.
All these amplifiers are compliant with the Radio Equipment Directive 2014/53/EU and meet the
harmonised standard EN 303 354 for Class 0. As such they work on ALL current UK DTT channels
including channel 60, are resilient to interference and overloading, and cope with multiple carriers. In
cases of strong LTE interference a separate 4G filter should be fitted. These are supplied free by at800,
or higher performance models can be purchased from www.blake-uk.com. (To pass channels up to
and including channel 59 use proLTE1/59, or if channels 58 and 59 are not required, use proLTE1/57).
Features:
•
Dual-mode operation: can operate as an aerial amplifier, or as a return-path amplifier with Sky*
remote control facilities.
•
Flexible powering options: 5 - 15 V (local or remote) for aerial-amplifier mode; 9 V from Sky*
receiver for return-path mode.
•
Automatic mode selection. 2-colour LED indicates operating mode.
•
Excellent low noise figure and output capability.
•
Input filtered below 470 MHz to reduce risk of interference problems from CB, private mobile
radio, TETRA, etc.
•
Suitable for both digital and analogue applications, fully DTT-compatible.
•
Channels 61-68 can be used for locally modulated signals.
Application guide:
See application example diagrams on page 2.
Mode 1 aerial amplifier mode (green LED): in this mode the unit functions as a straightforward 4-way
UHF amplifier. The input will usually come directly from the UHF antenna. Line-power (5 - 15 V DC) can
be supplied via any of the four outputs. Alternatively, if a mains supply is available near the amplifier, a
local AC/DC mains power adaptor may be used instead of line-powering. In Mode 1 no power is passed
to unpowered outputs and the return-path amplifier function is completely disabled.
Mode 2 return-path mode (orange LED): this mode is automatically enabled when the amplifier is
powered via its input. Usually the input will be fed directly from the second RF output (RF OUT-2) of a
Sky Digibox or Sky+* receiver or a Sky Digibox with an I/O port
enabled (see over). In return-path mode power is present at all outputs for powering remote infrared
receiver eyes, such as the PROception proSAT1EYE. Infrared receiver power is individually short-circuit
protected, so that a DC short at any output will not affect operation of remote control via the other
outputs.
The relatively low forward gain of the amplifier (4 dB) is sufficient to compensate for additional
downlead cable losses in most systems, whilst avoiding intermodulation and other overload problems
which easily result from the use of excessive gain. Where more gain is needed in aerial-amplifier mode
(for example in installations with very long cable runs, or in weak signal areas) the proMHD14M or
proMHD14V 4-way masthead amplifiers should be considered instead (these alternative products do
not provide return-path capability).
