DB-15 External Antenna Select Input (Pin 1-4):
The RF2K-S internal controller can store tuner settings for up to 16 antennas
per band. Your external antenna selectors connect via the Ant 1 connector.
With this arrangement the amplifier must be made aware which of the up
to 16 antennas is in use. This is done by providing BCD data toPins 1-4 as
detailed in the table. Antennas may be mono or multi-band.

4. Preparing for operation
4.1 Unpacking
►After unpacking, inspect the device for shipping damages.
►Report any damage immediately to the delivery company and your
supplier. Keep the shipping box.
4.2 Scope of delivery
1x RF2K-S Power Amplier
1x 120 V AC line cord
1x 240 V AC line cord
1x Short coaxial cable with 1x SMA connector (“Pigtail“)
1x Micro SD-Card for operating system
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 socket 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 is pre-
sent.
4.7 Preparing LAN connection
►Connect a 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 socket using
suitable coaxial cable with as little loss of power as possible, and pro-
fessionally mounted PL-259 plugs to connector ANT 1 (6), ANT 2 (5),
ANT 3 (4), ANT 4 (3).
When device is switched o, TRX (17) is looped through to
ANT 1 (6) .
4.9 AC Line cord 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 to
approximately 900 W.
►Connect the device with the included line cord via Power jack (9) to a
properly installed power outlet.
