Individual Bandpass Filter
Gain peak receiving and transmitting performance from modern transceivers
and stop out-of-band energy from nearby transmitters with I.C.E.'s full
line of single band filter units Practically an international standard among
the top competition stations, government agencies, and disaster relief organizations,
bandpass filters are used widely to pass only the listed frequency segments
for which they are tuned blocking all frequencies above and below the passband.
Use bandpass filters anywhere that critical single band performance
is required, or where nearby transmitting stations cause interference
to needed communications. Excellent for multiple-operator stations, portable
or field use, indoor or outdoor service, non-polarized. Chose from listings

Combination Bandpass Filter
- NEW 419B Model
A reintroduction of a product first featured in 1994, Model 419B is a six
position bandpass transceiving filter for HF services. Constructed
in an I.C.E. standard heavy case measuring (HWD) 31/2"
X 71/2" X 8", Model 419A standard model features
the popular six Amateur Radio frequency bands 160, 80/75, 40, 20, 15 and
10 Meters in a manual or auto-switching circuit.
Individual twin tuned circuit bandpass sections are mounted to the copper
chassis with all connections soldered and joined with copper strap lines,
switched with double pole individually scaled RF relays. Band selection
is done from the front panel directly by the operator with the main knob
control or by automated means derived by ground closure to the 8-pin
DIN connector on the rear panel surface. Switching time 11 milliseconds,
voltage requirements 12VDC negative ground at about 100ma supplied to
rear panel through coaxial DC connector. Power rating 200W ICS. Unit
defaults to pass all signals directly through when power is turned off
from front panel. LED indicators show active band selected in either
manual or auto mode. New features in the "B" model include
DC fuse, AC or "dirty" DC capable to make Unit operable in
harsh locations. Weight 5 pounds.

HF Lowpass Filters
One of our most popular products
and sold worldwide, I.C.E. lowpass filters are a preferred standard among
commercial and private users. Lowpass filters pass frequencies below
rated cutoff pointwith little or no attenuation and harshly attenuate
frequencies above designated cutoff point (30 MHz).
Model 420 Series filters are heavily built deep notching Chebyshev designs
and are ideal for interference cases where harmonic or spurious energy
is either detected or feared, and a must for good station design.
All units now rated for higher power than previous versions. Low power
model 420 uses silver-mica capacitors, phenolic connectors, and available
in SO-239s or N connectors. Higher power models 421 and 422 use thick
(about five times the thickness of other manufacturers)
Teflon TFE insulation
sheet, brass or copper capacitor plates - and all connections are soldered
- no "pop" rivets. Cases are all single unit chassis, fully
shielded 1/8" thick 6063 aluminum extrusions.
All units come with 4-page owner's manual, connector covers, stainless
steel grounding terminal. Use with mounting
fixture for professional quality results.

VHF Lowpass Filters
Interference to other services is also commonplace when VHF transmitters
are being employed. Both low and high power versions of our popular
filters are offered below, and they may even be "stacked" for peak performance
(low power unit between transceiver and amplifier, high power filter on
station output). All devices provide harsh cutoff, high attenuation, solid
crush-proof design casing.
Similar in construction, appearance, size and weight to lower frequency
models detailed at right, Models 425, 426 have higher cutoff points and are usable to 54 MHz for transmitting
applications, ICS. Packed with 4 page owner's manual, these units also
fit perfectly with mounting frames.
TV Highpass Filters / AC Line Filters
Interference to television reception from nearby HF transmitters is common
and often a frustrating problem. Most disturbances are caused by simple
RF voltage overload and can be reduced or eliminated with no more than the
installation of an inexpensive highpass receiving filter.
Probably the world's only complete TVI prevention package. ICE's Model
430 Series units combine deep-notch low end cutoff attenuation slope
below television frequencies to stop differential mode interference,
input currents limiters to block strong signal overload, shield choke
for common mode (cable shield electrification) interference, and even
a front-end blocking circuit to isolate the TV set from the cable line
for added interference and over voltage protection.
Filter circuit is 11 sections overall, 75 ohms, and constructed in a
fully shielded 1/8" thick aluminum chassis housing with 'F' connector
female input and output for fast, convenient connection to line and receiver
Model 430B is a wide spectrum version passing all frequencies from 54
to 500MHz Other models are the same except with the addition of specific
wave traps to offer more attenuation to known interference frequencies.
Model 436B is a suck-out version specially designed for interference
caused by a nearby FM radio station. Notch to FM band peaks at about
25db, internally adjustable. Model 437B is similar but notch range is
Amateur 2 Meter band (144-148Mhz), also internally adjustable by coil
placement. Both units are tuned to the center of each undesired frequency
Filters are individually bagged with 4-page owner's manual. Each measures
3" square by 1" high, insertion loss 1-2dB, weight 1 pound.
TV Bandpass Filters
If you use a VCR or cable channel
converter with a single channel output (channel 3 or 4), here's an inexpensive
way to provide additional off-frequency attenuation and clean output.
Models 434B (Channel 3) and 435B (Channel 4) allow the passage of the
single channel while attenuating all frequencies both above and below
the channel. Each filter also contains a shield choke input to block
external currents possibly traveling on the cable shield, input limiter
circuitry, and even front-end capacitive blocking to isolate the filter
circuit from the line.
Units are 75 ohm, non-DC passive, and are identical in appearance and
size to highpass filters shown above.
BCB Interference Filters
Happy customer " I received
the filter in good order, it has given me back 160 meters,
this band was useless before the filter and now it is 100%
usable. Thanks for a superb product at a totally reasonable
price." de VE3XQQ..... Frank
AM broadcast stations transmitting in the frequency range from 550kHz to
1700kHz cause havoc with HF and VHF receiving operations, often inducing
carriers, modulation, broadband noise and other disturbances into delicate
Such interference can frequently be heard mixing with other received
signals in the shortwave bands and commonly overwhelms front ends of
Broadcast reject filters reduce AM band signals to levels where local
Stations can still be received in most cases, but are no longer threatening
to other desired services. A must for serious low frequency DXers or
Amateur 160 Meter enthusiasts. Five models are available for both receive-only
applications or for use with transceivers (allows transmission of up
to 300 watts through the filter above the rated cutoff frequency).
Model 401 is for reception only and is designed to notch out the BCB
band from 550kHz or 1700kHz, allowing reception of signals below 500
kc and above 1.8 MHz Model 400 units are designed to operate above 3.5MHz
These two models are for reception only (400) or transceiving (400X)
and, both units place the BCB band frequencies and below well into the
stopband, inserting very high attenuation even at the higher end of the
BCB band frequency segment.
Model 402 and 402X are receive only and transceive models respectively,
and designed for use all the way down to 1.8 MHz, attenuating everything
Each filter is individually bagged with owner's manual, weights all
1 pound. Receive only filters are fitted with RCA pin connectors (or
SO-239 connectors on request), while transceiver models are all SO-239s.
