1.3 Environment protection
Disposal of packaging
The packaging protects the device against damage during transport. The
packaging materials are selected according to environmentally friendly
and disposal-related aspects and thus recyclable.
The return of the remaining packaging parts, such as packaging straps, PE
bags, etc., into the material cycle saves raw materials and reduces waste.
Your dealer takes back these packaging parts generally.
If you dispose the packaging parts by yourself, please ask for the address
of the nearest recycling center!

Operating and installation instructions RF-KIT Power Amplifier RF2K-S
This device is NOT a TOY. It must not be handled by children or placed
within reach of children or even been operated.
The unit should only be opened or serviced by a qualied technician.
This device generates high frequency energy. Use the device with due
care regarding the system conguration.
When connected to an antenna, this linear amplier can generate
high-frequency electromagnetic elds, which must be evaluated ac-
cording to applicable national laws. All measures must be taken to
ensure the necessary insulation regarding human exposure (observe
minimum distances!).
The radio frequency energy generated by this device may interact
with some electronic devices such as pacemakers and debrillators.
Refer to the manufacturer instructions of a pacemaker or debrillator
for precautions in the vicinity of a radio frequency transmitter.
Immediately stop an ongoing transmission if malfunction or interfe-
rence with a pacemaker or debrillator is suspected!
DANGER - HIGH TENSION!
NEVER connect an antenna or remove an antenna
connector while the unit is transmitting!
This can cause electric shock or burns!
DANGER - HIGH TENSION!
NEVER operate the device without properly
mounted cover.
This can cause electric shock or burns!
DANGER - HIGH TENSION!

cause an electric shock!
WARNING!
NEVER operate the device with a mains voltage
other than the recommended 110-240 V mains
voltage.
This could cause a fire or destroy the device!
WARNING!
NEVER operate the device together with an
extension cord or multiple socket.
This could cause a fire or electric shock!
WARNING!
NEVER allow pieces of metal, wires or other
objects to touch the internal parts or connectors
on the back of the device!
This can cause electric shock or burns!
WARNING!
NEVER leave children alone with the device ready
for use!
Risk of injury due to electric shock!
WARNING!
The device is intended only for indoor use. NEVER
expose the device to liquids and NEVER operate it
in a humid environment!
This can cause electric shock, burns and destroy
the device!
WARNING!
The device gets hot during prolonged transmis-
sion operation!
NOTE:
Avoid using or installing the device in environ-
ments with temperatures below -10 ° C (+ 14 ° F)
or above + 40 ° C (+ 104 ° F).
Avoid the exposition to direct sunlight onto the
device and operation in extremely dusty env-
ironment.
NOTE:
Place the device only at a well-ventilated place!
Make sure that no objects are placed on the
device or near the ventilation openings, which
will hinder the heat dissipation.

4. Preparing for operation
4.1 Unpacking
►After unpacking, inspect the device for shipping damages.
►Report any damage immediately to the delivering freight forwarder
or dealer. Keep the shipping box.
4.2 Scope of delivery
1x RF2K-S Power Amplier
1x Power plug to assemble a country-specic AC power cord
4.3 Selecting a location
Because of its weight the device must be situated on a stable surface.
►Select a location for the device that ensures adequate air circulation
(at least 10 cm of free space in front of and behind the PA are
neccessary).
►Avoid locations with extreme heat or cold, high humidity and
vibrations.
Avoid operation near TV sets, television antennas, radios and other elec-
tromagnetic sources.
4.4 Grounding
WARNING!
NEVER connect the Ground connector (11) to a
gas or power line, as this may cause an explosion
or a electric shock!
To prevent electric shock, television interference (TVI), radio interference
(BCI) and similar problems:
►Ground the device via the ground connector (11) at its back.
For best results, use a copper wire with large cross-section to connect
to a copper rod, as long as possible, buried in conductive soil.
►Keep the length of this copper wire as short as possible!
4.5 Connecting exciter
►Connect the antenna connector of the exciter (a transceiver in general)
to the connector TRX (17) of the PA via a coaxial cable.
4.6 Connecting PTT-cable
►Connect the PTT connector of the exciter (a transceiver in general)
to the connector PTT (7) of the PA via a RCA cable.
At the center contact (+) of the connector PTT (7) +5 V are
present.
4.7 Preparing LAN connection
►Connect the supplied ethernet cable to the LAN (13) socket.
►Connect the ethernet cable to the router / switch of your local area net-
work.
4.8 Connecting antenna(s)
Do NOT transmit without an antenna or dummy load connected! Select
one or more 50 Ωantennas or dummy load with 50 Ωlead and more than
2 kW rated power.
►Connect 1-4 antenna(s) to the desired 50 Ω antenna connector using
suitable coaxial cable with as little loss of power as possible, and pro-
fessionally mounted SO-239 plugs to connector ANT 1 (6), ANT 2 (5),
ANT 3 (3), ANT 4 (4).
ANT 1 (6) is looped through as long as device is „o“.
4.9 AC power cable connection
The device works with mains voltages between 90 and 290 V AC. We re-
commend the use of 200-240 V / 50-60 Hz AC to ensure the full performan-
ce of the device.
if the device is operated at 110 V, the maximum output power drops from
approximately 2000 W to approximately 900 W.
►Connect the device with the self-assembled power cable via power
jack (9) to a properly installed power outlet.

6. Antenna tuner
6.1. Operation
The LC network in a antenna tuner is to compensate reactive components
and to provide power adjustment, so the antenna radiates supplied TX
power Peff via the radiation resistance R.
This requires:
- compensation of reactance jX = j(ωL-1/ωC) of the antenna system
and
- transformation of the effective resistance for power adaptation of the
transmitter to the antenna system.
(Antenna system = antenna + impedance transforming feed line).
Available values of C: Minimal 0,0 pF; Max. 1275 pF
Available values of L: Minimal 0,0 μH; Max. 10,16 μH
The integrated antenna tuner can perform this „at the push of a button“ for
you automatically (tuner mode „AUTO“). In this mode, the antenna tuner
automatically determines the required configuration and does all settings.
Beside of that, you have the option of performing the tuning process
manually (tuner mode „MAN“) or refine a configuration that has already
been determined before.
Regardless how a setting has been determined, all of the values can be
stored for later retrieval, so a re-tuning process is superfluous.
A separate database will be created for each antenna connector, in which
all already determined settings for this antenna will be stored.
Depending on the currently selected antenna connector, only settings
stored for this antenna connector will be considered during operation. The
antenna tuner continually checks for the availability of a suitable, already
stored setting for the currently selected antenna connector while tuning
a frequency.
