I. Introduction
SMART handy 3 is series of multi-band TV amplifiers assigned for use in antenna systems receiving
terrestrial TV programs in detached houses, residences, terrace houses, hotels, boarding houses, holiday
centres, schools, hospitals, etc. - even situated in places with difficult reception conditions, where the
received signals have different levels and are coming from different directions. SMART handy 3 amplifiers
can be used as an independent unit, as a part of a multiswitch system as well as a part of a simple head-end
station.
The automatic level adjustment function of the amplifier enables easy and fast installation. SMART handy®
can also be used for transmission of adjacent TV channels. The amplifier is especially suitable for receiving
terrestrial digital TV signals (DVB-T).
II. Product features
 Selective, independent amplification for 8 channel paths in UHF range
 Possibility of expanding channel path up to 6 TV channels (8…48MHz)
 Supplies antenna’s preamplifiers for UHF1-UHF3 inputs
 On-board preamplifiers status indicator – two-color LED diode
 Prepared for analog and digital Terrestrial TV signal – DVB- T
 Low-power consumption
 Easy installation and activation
SMART Handy 3 is equipped with 8 channel paths P1…P8 for UHF1-UHF3 inputs. Every channel has an
adjustable filter, which can be tuned in range of 21…69 . Furthermore frequency band of every channel may
be expanded from 8 up to 48 MHZ ( 1 up to 6 TV channels ). UHF1- UHF3 inputs enable to supply
preamplifiers with +12 V or +24 V voltage. If preamplifier power supply is not needed you can disable it by
removing the jumpers located near each UHF input. In case of short-circuit (closed shield with concentric
cable core or low impedance), state will be immediate indicated by red color of LED diode located near
proper UHF input.
UHF 4 input (AUX – 470…862 MHZ) enables connection of additional devices such as: video camera,
satellite receiver, DVD player etc.
III. Installation
The amplifier should be activated only after mounting is completed and correctly directed antennas
have been connected. Minimum and maximum TV signal levels are shown in the table Technical
specification at last page.
1. Connect the antennas as follows:
- VHFIII-band antenna to VHF input,
- UHF-band antennas to UHF1, UHF2 and UHF3 inputs,
- FM antenna to BI/FM input.
Note: UHF1 input is recommended for the antenna receiving the biggest number of UHF channels. ?????
It is possible to connect to UHF1, UHF2, and UHF3 inputs antennas with preamplifiers. To turn on the
preamplifier power, jumper should be placed near proper UHF input. In case the power supply is not needed
jumper should be displaced.
According to amplifier’s location (place of installation), the correct number of channel paths P1…P8 (filters)
should be assigned to proper UHF1-UHF3 inputs.
Table 1 specifies possible combinations of channel paths for UHF1-UHF3 inputs. For example, if every TV
signal is coming from one direction, you should choose 8/0/0 key setting and connect receiving antenna to
UHF1 input. Remaining and unused inputs should be closed with 75 resistors.

Caution!
“AGC” mode doesn’t allow an

In this mode you can only turn
off/on AGC function.

3. Power supply settings for preamplifier
UHF1, UHF2, UHF3 inputs are supplied with
+12V or +24V voltage. Turning on the powe
r
supply is done by placing an jumper near the
proper input (DC ON).

4. Programming of channel paths UHF 1 – UHF 3
Each of P1…P8 channel paths is designated for transmission from 1 up to 6 adjacent TV
channels (filter’s frequency band is 8 MHZ up to 48 MHZ).
Choice of UHF channel for
P1 path
22-24 setting means that
channel path p1 is set for channels:
- initial k.22,
- final k.24,
- filter band 24 MHz
22-22 setting means that
channel path P1 is set for channels:
- initial k.22,
- final k.22,
- filter band 8 MHz

5. Fine tuning function
In particular cases, when automatic tuning to middle frequency of the channel is not giving subjective effect,

. Input signal regulation
manual retuning of some channel paths might be needed. This might happen in several cases:
from the same antenna – in this situation it’s recommended to “move away” filters from each one
Reflection appearance (two images occurring – the correct one and moved one ), caused by
receiving strong signal near weak signal from different antennas – in this situation it’s recommended
to “move away” filters from each one
