Coaxial Impulse Suppressor / Arrestor
Like no other protective device in the world for RF coaxial cable lines,
patented 300-Series arrestors offer a complete, nearly perfect blocking/shunting
system for induced voltages. Whether produced by lightning (directly or
indirectly coupled), wind, rain, or snowfall I.C.E. arrestors are continuously
active, constantly draining transmission line center conductor to ground.
The result? Solid protection for station equipment and related noise.
All 300 Series units feature heavy discharge toroidal inductors used
to neutralize developed voltages on the antenna side of a central high-voltage
blocking capacitor. Inert gas tubes are used to limit the natural back-EMF
voltages often induced across an inductor when large fast rising input
currents are presented to the unit.
Sold and used worldwide, our arrestors are the first line of defense
in lightning protection employed by such services as the U.S. Army, Boeing
Corporation (Commercial Airplane Division), AT&T, MCI (Offshore RTTY
Services), and a wide variety of Commercial Broadcast, Public Safety,
Emergency Relief, Government, and Amateur interests. Our arrestors can
be found in the most stark surroundings, from dense African jungles to
the vast wastelands of some of the world's most punishing deserts. You
can even drive a truck over the top of the chassis without damaging the
contents (actually, you can do that to most I.C.E. products).
Available models cover the frequency range from as low as 100KHz to
with lots of connector choices. High power units feature
while low power units are outfitted with phenolic-style connectors. All
may be mounted on flat surfaces, grounding bulkheads, or through-mounted
using dual stainless steel grounding screws for mechanical fastening.
Packaged with 4-page informative owner's manual.
The arrestors are approx 3X3X2 inches.
These arrestors go the extra step to assure the maximum
protection. Learn why they are the finest arrestor

VHF/UHF/Microwave Coaxial Impulse Suppressor
Coaxial lightning arrestors for frequencies above 50 MHz use the same technology
as lower frequency units described above and are all constructed in our
standard arrestor housing which is detailed mechanically below (see graphic).
Even-numbered 302, 304 and 306 series units are ideal for terrestrial
repeater or point-to-point services, commercial broadcast or cellular
applications, long distance scatter, EME, etc. Each unit includes high
voltage blocking between input and output ports with antenna side of
arrestor connected through near dead-DC--short inductor to ground (case),
draining center conductor of system continuously to earth connections.
All units are available with DC insertion modification which allows duplexing
of AC or DC voltage through arrestor into transmission line to power
mast-mounted preamps, switching, etc. To order, these parts have a "DC"
suffix. Also state operating voltage and we'll construct the unit to
provide close-in overvoltage attack, dual polarity. Voltage insertion
is done from protruding hardware in top of arrestor through ground-lifted
Open Wire Arrestor
For transmitting or receiving applications
using open-wire fed systems in single wire or parallel balanced lines,
these arrestors use our patented technology in larger housings with insulated
terminals. Low power units are constructed in metallic aluminum chassis
cases while high power arrestors are in PVC Weatherproof NEMA-style cases
manufactured by CarlonCo. (Shielding of open wire arrestors is not necessary.)
ModeIs 308 and 308H are designed for use with open single wire systems
such as tuned longwire antennas and random wires added with antenna tuners.
Both are compatible up to their design power ratings with a wide variety
of input impedances / reactances ranging from about 300 ohms to 600 ohms
Like all arrestor protection units these circuits are designed to be
ground-mounted and should be installed close to earth entry point connections
for best results.
Models 309 and 309H are configured for open wire balanced feed systems
in the same impedance range as mentioned above. Compatible with both
split capacitor type antenna tuner and balun output stages common in
modern antenna tuning products.
All units use torroidal inductors and present near dead DC short on
antenna side of arrestor, constantly draining feedline wires of static
and any developed voltage potential feedthrough breakdown voltage from
input ports to output ports 4,000 to 6,000 volts. Arrestor units may
be placed anywhere in the feedline at ground level without serious change
in tuning, but small change may be detectable due "to small"
increase in total feedline length caused by size of arrestor case &
Models 308 and 309 series all rated for frequency range 1-30 MHz, non-DC
continuous through ports, polarized. Low power units 308/309 constructed
in aluminum cases measuring (HWD) 11/2" X 2"
X 3", high power units 308H / 309H offered in NEMA PVC cases measuring
4" square, 2" 'high, brass connection hardware. All units packed
with 4-page owner's manual.
& Video Base Band Arrestor
Modern television and FM stereo systems
are the most delicate ever built and can be easily damaged by voltage
transients delivered by outside antennas or commercial cable systems.
Cable companies offer little, if any, lightning protection and are not
responsible for resultant damage when it occurs.
Model 310, 311, 312, 313 and 317 offer do-it-yourself protection and
easy installation in just about any home or institution based system.
Each is completely shielded and constructed in an aluminum case for indoor/outdoor
services. The only other installation requirement is a ground rod earth
terminal connected to the chassis.
Model 310 is a CATV arrestor designed for use with all receiving systems
using coaxial cable and operating between 50MHz and 1 Ghz. (Commercial
cable Systems operate mostly between 50 MHz and 500 MHz) This unit uses
our patented high isolation blocking technology with inductor shunt output
protection. "F" connectors standard, 75 ohms.
Model 311 is similar but allows insertion of AC or DC voltage up to
50 Volts for powering mast-mounted preamplifiers in home systems. Current
rating 5 amperes maximum.
Model 312 is new for 1998 and is also a blocking unit similar to Model
310 but features an expanded frequency range from 1.5 MHz to 1,000 MHz
for cable systems that offer two-way interactive features. Compatible
with upgraded fiber optics cable networks and expanded channel services.
Model 317 is also similar to basic Model 310 but includes signal spark
protection for higher sensitivity reception systems. This unit limits
signal input during lightning disturbances to the receiving set's terminals
to about 500 millivolts.
Model 313 is designed for 300 ohm open wire "ribbon" line
in outdoor-antenna systems, frequency range 50-1,000 MHz, DC blocking.
All units packed with 4-page owner's manual / instructions.
Model 320 is designed for CCTV 75 ohm applications, it
is a DC blocking arrestor with BNC connectors.

Designed especially for TVRO
Satellite and DBS home dish systems, these arrestors are DC passive to
a flow tuning voltage to pass-through to dish-mounted electronics. Units
work with older 8-10' dish systems and all brands of later DBS products
using 18" higher frequency dishes. The use of arrestor
protection in all such systems provides earth ground neutral for dissipation
of static and coaxial line electrification caused by overhead discharges.
Model 315 employs hybrid circuit of both gas discharge device and metal
oxide varistors for fast attack speed, DC voltage passive up to 50 volts
non-polarized, screw-in "F" connectors standard Frequency range
900-1500 MHz, 75 ohms impedance.
Model 316 is a combination unit which includes the circuitry from Model
315, and also a control wire protection system similar to our Model 348.
Up to 8 conductors, maximum 50 Volts AC or DC may be used for azimuth
/ elevation control of satellite receiving dish antenna.
All units are constructed in aluminum cases stainless steel ground bolts
protrude from the sides for making earth ground connections, or flat
surface mounting. Model 315 is identical in size to other arrestor products
at (HWD) 11/2" X 13/4"
X 21/4". Model 316 measures 3" square
by 21/2".tall. Each unit packed with 4-page
owner's manual / guide.
Arrestor Mounting Fixtures
Industrial mounting frames are used with I.C.E. 300 Series Lightning Arrestors
for attaching units directly to ground rod tops (keeping lead inductance
to a near-zero minimum). This mounting method provides the highest possible
performance for voltage protection. And they're built as if we're expecting
you to be hit time after time. Upper horizontal mounting plate is pre-threaded
and 1/2" thick solid 6061-T654 I aluminum bar stock, tower section
is prefitted at factory and measures a bruising 1" X 11/2"-
solid. Set screw that holds assembly to ground rod is stainless steel 1/4-20
Phillips head, balance of mounting hardware also 18-8 stainless steel.
Boring of lower section is designed to comfortably fit top of ground
rod by simply sliding the whole assembly over the top of the rod after
coating both surfaces with conductive copper-loaded anti-oxidant compound
(provided). Bore, size is approximately .015-.020 larger than rod to
keep the fit tight, the frame horizontal, and prevent entry of moisture,
dirt, insects, etc.
Units are machined in one, two, and four-unit varieties indoor or outdoor
use, accepts direct rain / snow exposure. Each unit is packed with anti-oxidant
compound, #8-32 screws for arrestor chassis mounting, weight approximately
