Introduction
 ISDB-T, TDT DVB, DVB-T, ATSC-M/H Standards Are in Place in
LATAM
 ALL of These Standards Support Broadcast to Mobile Receivers
 This is THE Time for Broadcasters to Move Ahead of Competitive
Delivery Methods (Satellite, Cable) While Keeping The System
Flexible Enough for Future Enhancements/Expansion
 What Does the Broadcaster Need to do to Take Advantage of
Standards and Technology to Gain An Advantage Over Competitive
Delivery Methods and Competitor Stations?

Polarization Diversity……

Polarization Diversity Continued
 Studies Have Shown That by Adding a Vertical Component to the
Radiated Signal Increases the Margin at the Receiver by 2 to 11db
 How Can This Be Achieved?
Elliptical Polarization or Circular Polarization From a Common
Array
 Is There a Way to Upgrade The Antenna System Today While
Allowing for Future Polarization Ratio Changes As the Business
Model Focus Transitions to Mobile?
 Absolutely-Using Variable Polarization Technology (VPT)!
29

Variable Polarization Technology (VPT)
VPT Allows for Each Channel in a Master Array to be Operating with a
Polarization Ratio Independent of the Ratios of Other Channels
Operating in the Same Array
Stations can Operate Horizontal Polarization, Elliptical Polarization and/or Circular
Polarization Simultaneously in the Same Array
Why is This Important?
Today’s Polarization Ratio is Typically 100% Horizontal (Just Upgraded DTV
Transmitter) and Additional Transmitter Upgrades in Coming Years
Determining What the Right Polarization Ratio Can be Dependant on Channel of
Operation, ERP, Terrain, Competition, Transmitter Limitations…Not the Same For
Every Broadcaster
The Polarization Ratio May Change as the Business Model Matures and Supports
Mobile Reception
System is Future-Proof! Allows for Future Polarization Ratio Changes Without
Antenna System Changes!
Allow Stations to Leap Frog the Competition on Their Time Frame

Band IV/V (UHF) PeakPower+TM bandpass filter.
•
35
The Peak Power+ line of filters and
combiners have been specifically
conceived for the very high peak-toaverage power ratio nature of digital
television (DTV), and represent
a breakthrough in coaxial filter
technology.
© Radio Frequency Systems 2011 All rights reserved
Band IV/V (UHF) PeakPower+TM bandpass filter.
• Very compact for easy integration into
equipment.
• Very low insertion loss for filter size,
(lowest IL for this size).
• Highest power rating for size/class of filter.
• Tunable over full UHF band (470 – 862
MHz)
• Adjustable bandwidth, available for 6, 7 & 8
MHz channels for global
applications.
• External, non-invasive coupling
adjustment.
• Tunable for both ETSI and ISDB-T critical
and non-critical, and ATSC
applications.
• -5 to 55 degree ambient temperature
operation.
