AMERITRON RCS-4 Remote Coax Switch
Ameritron RCS-4 is a
remote controlled coax
switch that selects 1 of 4
outputs by supplying all con-
trol voltages through the coax.
Elimination of control cables gives you
a fast, neat and inexpensive installation --
only 1 coax line for 4 antennas.
Yo u get two units -- the switching box
(5

mast or wall mounted and the control con-
sole (6

located at your operating station.
The attractive indoor console has bright
LED antenna selector indicators.
A steel enclosure provides 100% shield-
ing to prevent RFI and TVI.
Switching time is 50 milliseconds.
Teflon

SO-239 connectors provide reli-
able connections.
The weatherproof switching box uses
three heavy duty 16 ampere hermetically
sealed relays on a rugged G-10 fiberglass
circuit board.
Quality components are used through-
out the entire unit to ensure maximum life
for the sometimes difficult-to-reach switch-
ing box.
RCS-4 operates 120 VAC. RCS-4X for
220/240 VAC. RCS-4 allows safe opera-
tion with 14 Volts control voltage.
Frequencies 1.5 - 100 MHz are covered
by this excellent station accessory.
Handles over 2.5 kW.
Specifications:

When you first
turn on your
amplifier, a mas-
sive inrush current
gushes in.
House lights
flicker as you hear
a loud “thump” from your amp.
This terrible inrush current stresses
all your power supply components
to their limits. Your cold tube fila-
ment suffers abusive thermal shock.
Eventually this massive inrush cur-
rent will damage your amplifier.
Ameritron’s Step-Start Inrush
Current Protector
TM
stops damaging
inrush current.
By starting your linear amplifier
through a high power current limit-
ing resistor and then shorting the
resistor with a relay, the start-up
sequence is easier on tube and
power supply components.
All Ameritron kilowatt amplifiers
have this critical protection. Now
you can add this protection to your
amplifier without complicated
wiring -- you don’t even have to
take the cover off.
Simply plug your amplifier
power cord into the Ameritron
Inrush Current Protectior
TM
.
Limiting heavy inrush current to a
safe, low level, you get a longer
lasting amplifier.
Yo u might avoid replacing
expensive tubes and components.
Avoiding just one repair job could
pay for this extended protection.
Momentary high-voltage
“spikes” in the AC line can also
cause damage to your amplifier.
The ICP-120/240 has built-in varis-
tors to absorb these spikes before
they can cause damage. Works with
nearly all linear amplifiers.
Ameritron ICP-120, $79, for
120 Volt wired amplifiers.
Limits current to 12 Amperes
during heavy draw inrush period.
20 Amperes during continuous oper-
ating current.
Ameritron ICP-240, $79, for
240 Volt wired amplifiers.
