Control process to ensure correct
output power stability, and the
monitoring of key transmitting
power figures such as Forward
Transmitted Power and Reflected
Power levels. It's also been expanded
from its original DVB-T and DVB-T2
specification to support ISDB-T/TB
and DTMB standards, which will help
Teamcast push it into markets in
South-America, Philippines, China and
Cambodia. Naturally, it also provides
the opportunity for TX manufacturers
who have already integrated it within
their designs to enlarge their business
footprint, which is always a handy
thing.
The company has also been making
noises about the advantages that
combining its Stream4CAST Scheduler/
Gateway and its exTra3.0 exciters can
bring to an industry looking for an
ATSC 3.0 Single Frequency Network
solution. Used in combination with
the exciters, a Stream4CAST located
at the head-end or at the Network
Operating Centre is responsible for
the generation of the Studio-ToTransmitter data stream to feed the

different transmitter sites, all of
which allows broadcasters to perfectly
synchronise the RF signals radiating
from several transmitting sites.
ENENSYS Networks introduced
a new product at IBC designed
to provide highly cost-effective
retransmission of DTT networks at
regional/local transmitter sites where
microwave, fibre or copper IP or
satellite connectivity isn't possible, or
is cost-prohibitive. Its DTTCaster allows
reception of the network content using
a simple antenna then re-generates
that content on another frequency. The
content remains exactly the same and
is SFN-compliant. Up to six DTTCaster
units can be housed in a 1U chassis
and each unit can receive up to four
RF signals from a single DTT antenna,
and rebroadcast them in DVB-T/T2/
ISDB-T/Tb for DTT retransmission sites
or cable head-ends.
Dielectric has been concentrating
on radio of late. It first introduced
its field-tuneable, FM two-channel
combiner back at NAB in April, happily
pointing out the cost and space savings
it provided by eliminating the need for
eliminating coaxial tee junctions and

associated coaxial line and
elbows through an RF plant.
More recently, its Manifiold
Combiner is targeted at FM
stations in the 1 to 20kW
range and can be specified
for use with any master

ADBL For UHF
Broadband Solutions

A

lan Dick Broadcast Limited
(ADBL) has highlighted its unique
concept-to-installation solutions by
featuring a variety of UHF Broadband
Solutions.
Broadband UHF panel antenna
are available for Bands IV & V in all
polarisations: CPOL, EPOL, HPOL and
VPOL. The antenna is designed as
either a side-mount or a top-mount for
DTV, ISDB-T, DVB-T/T2, NTSC or PAL
broadcasting.
With elliptical or circular polarised
broadband panels, ADBL offers dual/
individual inputs for horizontal or
vertical polarisation which allows for
varying levels of polarisation split and
pattern performance.
Both versions are engineered and
well suited for digital/analogue TV
and mobile video. Built with corrosion
resistant stainless steel and aluminium
reflecting panels, the antennas are
designed for long lasting durability.
Match this broadband panel antenna
with one ADBL's combiners and/
or mask filters designed to provide

superior mask filter performance at an
affordable price.
