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)!


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 YearsDetermining 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.

• The Peak Power+ line of filters and

combiners have been specifically conceived for the very high peak-to-average power ratio nature of digital television (DTV), and represent

a breakthrough in coaxial filter technology.


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 globalapplications.• External, non-invasive coupling

adjustment.• Tunable for both ETSI and ISDB-T critical

and non-critical, and ATSCapplications.• -5 to 55 degree ambient temperature

operation.
