Dielectric Reorganizes RF Team
for the Post-Repack World
W

ith the spectrum repack fully in
the rearview mirror, Dielectric
has promoted Mike Spugnardi
to Director of RF Systems and
Components as the company shifts its
strategy to better serve broadcasters in
the post-repack world. As TV Antenna
Manufacturing Manager, Spugnardi
applied his extensive Dielectric
experience to lead all strategic repack
initiatives around inventory control,
production planning and maximizing
capacity. His successful strategy
ensured that more than 1000 repack
customers were transitioned to new
channel assignments within very tight
timelines.
In his new role, Spugnardi will
bring that same strategic focus
to the company's RF Systems and
Components division. This includes
new product designs that reflect
changing customer needs in today's
reduced UHF spectrum in the United
States, as well as making products
more efficient for international TV
and radio customers.

" Mike's emphasis on
the finer details was
a primary reason we
were so well-prepared
for repack, which was
arguably the busiest
period of Dielectric's
nearly 80 years of
existence, " said Cory
Edwards, Director of OEM,
Distributor and Southeast
Asia Sales. " He is now
leading the charge with
an emphasis on new products and
existing product redesigns, particularly
around our UHF TV filters. "
Edwards explains that many of
these changes optimize Dielectric's
bandpass filters for Channels 14 to
36, which represent the post-repack
UHF band in the United States and
much of the Global Broadcast market.
In addition to redesigning existing
filters, the company is adding models
to serve increasingly common power
levels. This includes 5kW and 22kW
(pictured) models that will allow

Dielectric to provide more efficient
single-filter designs for these power
level requirements, while providing
additional headroom to accommodate
the higher peak powers of ATSC 3.0.
Such ATSC 3.0 requirements have been
at the forefront of Dielectric's designs
for many years, and continues to be a
key design criteria.
Spugnardi explains that even minor
filter design changes can make a big
impact.
One such change has led to a
significant improvement in the

company's medium-power, eightpole filter designs. The new design is
now manufactured as a single-piece
with an increased power rating of
22kW. The single-piece design will be
far more robust during handling in
shipment and installation,
easily retaining all factoryachieved tuning settings.
For Spugnardi, it's all
about better serving their
customers.
" Over the repack period,
we discovered that more
of our customers opted
for
eight-pole
filters
in an effort to reduce
spectral overflow in newly
congested markets. " said
Spugnardi. " Our previous 20 kW eight
pole-design had slightly more insertion
loss than the new design, and often
required small tweaks after shipping
and installation.
" This was not desirable given the
rapid pace at which repack progressed.
The new 22kW filter cavities are
optimized to improve performance,
efficiency and footprint. Our customers
now have a rock-solid filter with lower
insertion loss that is more efficient to
install and maintain. "

Riedel's MediorNet MicroN UHD Solution
Deployed at Betamobil
R

iedel
Communications
has
announced that Betamobil, a
Berlin-based provider of advanced OB
production facilities and services, is
the latest European customer to adopt
Riedel's new MediorNet MicroN UHD
media distribution and processing
solution. To support its ongoing
migration to IP-based operations,
Betamobil has deployed 14 MicroN UHD
devices to handle decentralized signal
routing on board its flagship OB van recently renamed UHD5 to reflect its
upgrade to advanced UHD production
capabilities.
Introduced last year, MicroN UHD
is the latest generation of Riedel's
award-winning MediorNet MicroN
family of modular, high-density signal
interfaces, bringing more bandwidth,
more I/O, higher resolutions, and more
processing power to the MediorNet
platform.
Reflecting
Riedel's
distributed and software-defined
approach to signal transport, several
of UHD5's MicroN UHD modules have

been configured as multiviewers using
the MicroN UHD MultiViewer App.
" Prior to installing the MicroN UHD
devices, we had to use separate
devices to handle video routing,
multiviewers, and signal processing.
Besides injecting more complexity
into our OB operation, the extra
equipment, connections, and cables
added weight and took up too much
space, " said Thomas Busch, Chief
Technology Officer of Betamobil.
" With integrated processing features
like
embedders/de-embedders,
the MicroN UHD with MultiViewer
App has provided an outstanding
solution. MicroN UHD is not only the
most flexible and scalable system
of its type on the market, but it also
offers superior price-performance,
which was a crucial factor in our
decision-making. "
In addition to the MicroN UHD-based
signal routing backbone, Betamobil
has chosen Riedel's Bolero wireless
intercom to form a fully integrated

point-to-point
intercom
ecosystem with an existing
Artist frame. With the ability
to deploy up to three Bolero
antennas and eight beltpacks,
Betamobil is able to extend
