Scala Electronic Corporation was founded in
California in 1954 and operated there until 1979
when operations were moved from the San Francisco
area to Medford, Oregon. In 1985, Scala began its
alliance with the Kathrein Group of companies, the
worldwide leader in professional antenna systems,
by distributing certain Kathrein antennas for the
emerging cellular market. Since then, Scala has been
fully integrated into the Kathrein Group. In addition to
its own designs, the company builds antennas having
their origins at Kathrein, but have been redeveloped
for the North American marketplace. With Kathrein
firmly positioned as the world’s oldest and largest
source of antenna and filter products for wireless
communications and broadcast technology, it made
good sense to align Scala with that visibility and the
company became Kathrein Inc., Scala Division on
January 1, 2000.
Over the past 58 years Kathrein Inc., Scala Division
has earned a reputation for products and service of
the highest quality as well as fair and ethical business
practices and we remain dedicated to these principles.
Through our full integration into the Kathrein Group
we are able to draw on greater resources and expand
our range of products and services while maintaining
the traditional Scala service and quality which our
customers have come to expect.
We welcome your inquiries and we look forward to
the opportunity to serve you!

SL-8
Paraslot® Antenna
The Kathrein Scala Division SL-8 Paraslot UHF-TV antenna is
a high performance slot array offering excellent performance
in UHF-TV transmit applications requiring omnidirectional
coverage. The SL-8 is available in single and multichannel
models with a 1,000 watt power rating and optional null-fill.
Kathrein Scala Division’s patented symmetrical parallel feed
system is completely housed within the center of the antenna,
and resists changes in radiation pattern caused by ice or snow
buildup on the periphery of the antenna.
The standard SL-8 is a single-channel slot array with a power
input rating of 1000 watts, VSWR of 1.1:1 maximum, 1.75
degrees of electrical beamtilt, and 7⁄8” EIA flange termination.
Options include null-fill and additional beamtilt.
The SL-8-2 is designed for wideband performance over two
alternate nonadjacent 6 MHz UHF-TV channels (e.g. Channels
60 and 62) permitting two transmitters to be diplexed into a
single antenna. The SL-8-2 provides VSWR of 1.15:1 or better
across the two specified channels.
The SL-8-3 Paraslot provides coverage of three 6 MHz alternate
nonadjacent UHF-TV channels (e.g. Channels 60, 62, and
64). This arrangement allows three UHF-TV transmitters to be
multiplexed into a single antenna. VSWR is held to 1.25:1 or
better over the three specified channels.
*Available for 6, 7, or 8 MHz channels in accordance with various
international channel allocation plans.

Reduction Of Co-channel Interference
Using Calculated Antenna Spacing
Co-channel interference can be reduced and in many cases eliminated completely by mounting
two or more antennas on the same plane (collinearly) and spacing them so that the unwanted
signal is rejected.
Theory:
When the angle between the wanted and unwanted signal is known, an antenna spacing can
be calculated to achieve maximum rejection of the unwanted signal. By using the calculated
spacing, the unwanted signal must travel 1⁄2, 11⁄2, or 21⁄2 wavelengths further to reach one
antenna than to reach the other. As a result, there will be a phase difference of 180 degrees at
the antenna combiner input, thus cancelling the unwanted signal. Because the antennas are
positioned so that the wave front of the wanted signal arrives at both antennas at the same time
and in phase, the wanted signal will remain additive.
Determining Antenna Spacing:
Two methods have been provided to determine antenna spacing. The first and most accurate
method is a mathematical formula provided below. The second method uses a graph provided
on the reverse side of this sheet. For both methods an accurate angle between the wanted and
unwanted signal must be determined (see Figure ’A’).
Using the formula, follow STEP 1
to determine spacing in wavelengths.
Then follow STEP 2 to determine
spacing in inches.
Where:
S = spacing in wavelengths
X = .5 wave, 1.5 wave, or 2.5 wave
A = angle between wanted and unwanted signal
F = frequency in MHz.
Abs = absolute value FIGURE “A”
134
FIGURE “A”
Fax: (541) 779-3991
Antenna Spacing For Maximum Cancellation
In Wavelengths
Using the graph, locate the determined angle
(bottom of graph), then find where it intersects
with the curve to determine the antenna spacing
in wavelengths (left of graph). Curve “A” will yield
the best results. If this spacing cannot physically
be achieved, use Curve “B”. Likewise, if Curve “B”
spacing is not possible use
Curve “C”.
Convert the antenna spacing in wavelengths to inches by dividing the number 11803 by the frequency
(in MHz.) and multiply the result by the calculated
spacing in wavelengths. This will give the spacing
from antenna center to antenna center that will yield
the maximum rejection of the unwanted signal.
EXAMPLE:
For the example we will assume that we have cochannel interference on VHF Ch. 5 and we determined
that there is a 25 degree angle between the wanted
and unwanted signal. The graph indicates that the
spacing for maximum rejection is 1.18 wavelengths.
The center frequency of VHF Ch. 5 is 79 MHz.

Increasing Front-to-Back Ratio
The front-to-back ratio of an array can be increased
considerably by using two identical antennas and a small
additional length of transmission line. One antenna is
mounted one-quarter wave length ahead of the other, and
the section of harness connecting the forward antenna is
one-quarter wave length longer than the section of harness
connected to the rear antenna.
THEORY OF OPERATION:
The desired signal arrives at the forward antenna onequarter wave (90 deg.) before it reaches the rear antenna.
However, since the signal from the forward antenna travels
through an additional one-quarter wave length of cable and
the signal from the rear antenna does not, both signals arrive
at the output terminal at the same time and phase.
Therefore, the two energies will be additive.
The undesired signal from the rear of the array will
arrive first at the rear antenna. When the signal reaches the
forward antenna it will be one quarter wave (90 deg.) out of
phase. This signal will then travel through the additional onequarter wave length of transmission line causing another
(90 deg.) delay. As a result the energy from the forward
antenna will arrive at the output terminal 180 degrees out
of phase with the energy from the rear antenna. These
two energies, being equal (in amplitude) and opposite (in
phase), will cancel leaving only the wanted signal.
Please note that one-quarter wave length in space
is greater than the one-quarter wave length used in
determining harness length. This is because the signal
traveling through space moves at a higher velocity than
traveling through coaxial cable. The exact velocity varies
with the charactersitics of each type of cable. Again it should
be emphasized that the above method of increasing frontto-back ratio will work with any type antenna, as long as
they are exactly identical.
To determine wavelength in inches, use the following formula:
11803
f
f = Frequency in MHz
Example:
Center frequency of Ch. 7 = 177 MHz
11803
= 66.68”
177
1
⁄4 wavelength = 16.66”
To convert inches to centimeters use the following
formula:
inches x 2.54 = centimeters
Again it should be emphasized that the above method
of increasing front-to-back ratio will work with any type
antenna, as long as they are exactly identical.

Painting Radomes of
Kathrein Scala Division Antennas
Formula For Estimating Gain For A Standard
Directional Dipole Array Using The E & H
Plane Patterns
With environmental and aesthetic issues becoming a
major factor in site acquisition, many of our customers are looking for ways to have their antennas blend
into the surroundings. Usually the easiest way to accomplish this is by painting. Below are some general
guidelines, should you determine a need to paint your
Kathrein Scala Division antennas.
*Gain (dBi) @ 10 log (32400/EH)
Kathrein Scala Division makes all its radomes out of
fiberglass, a material preferred by automobile makers because of its strength and stability over large
temperature variations as well as its resistance to
chemicals and air borne pollutants. For these as well
as other reasons, fiberglass is the best material for
making radomes.
Estimated harness loss 0.2 dB/meter of antenna length
Estimated connector loss
0.1 dB
E = E plane 3 dB beamwidth in degrees
H = H plane 3 dB beamwidth in degrees
Formula does not take into account losses for internal harnessing and input connector losses.
Printed circuit antennas have higher losses causing less
efficiency.
*R. S. Elliot, “Beamwidth and Directivity of Large Scanning Arrays” The Microwave Journal, January 1964
1. Prepare the fiberglass radome by cleaning it with
acetone. This will roughen up the surface and
improve paint adhesion.
2. Before applying any paint, be sure to mask the
connector and stainless steel mounting brackets.
This is very important to ensure a good electrical
connection to the transmit or receive equipment
and also to ground the antenna to the support
structure to provide a low resistance path to earth
during lightning storms.
3. Paint selection is very important as it must not be
an electric conductor. Certain metallic paint additives like titanium dioxide and zinc are allowable
as long as they represent less than 5%. Titanium
dioxide is a UV stabilizer commonly used in all
high quality fiberglass radomes to improves life
expectancy.
Keeping the above guidelines in mind, professional
looking paint finishes can be achieved by field personnel. For critical sites, it may be advisable to contact
an auto body shop to make an exact color match with
any building. This may entail a visit to the building to
obtain paint chips from the different exposures so that
aging and sun fading can be taken into consideration.
For further information regarding antenna painting or
mounting, please call Kathrein Scala Division at (541)

is the load
is the projected area of the antenna
is the wind velocity
is a constant unique to each antenna
Once the load f is found the resulting stress is found for
each antenna with its mounting system. The stress at
which failure occurs corresponds to a wind speed which
is termed “Wind survival”.

286 feet
Wind Survival Ratings as shown in this catalog represent
a mechanical design based on environmental conditions
as stipulated in TIA-222-G-2 (December 2009) and/or
ETS 300 019-1-4 which include the static mechanical
load imposed on an antenna by wind at maximum velocity. The static mechanical load f is found by the formula
as follows:
Operating conditions such as icing or exceptional
dynamic stress (such as strain caused by oscillating
support structures) may exceed the survival rating and
result in the breakage of the product or even cause it
to break away from its support and fall to the ground.
Please consider these facts during the site planning and
installation process.
