The mobile channel in UHF and VHF broadcast is described and extended to include transmission in two polarizations. Transmitting antennas that provide dual-polarized emissions are analyzed and found to be successful in improving reception with polarization diversity and increasing channel capacity with multiple-input multiple-output (MIMO) transmission.

This presentation will first look at the overall ATSC M/H system with focus on the physical, management and presentation layer activities. . The presenter will also look at RF transmission performance based on several years of first hand experience with the Harris-LG-Zenith MPH system which has been selected as the basis for the ATSC M/H standard. Recommendations for preparing a station for entry into the mobile services business will included.

Sure, you've heard the standard rule "No tighter than ten times the diameter." For some data cables, you might hear "four times the diameter." But what actually happens when you bend a cable? this presentation shows exactly what changes inside a cable and, for specific coaxes and twisted pairs, what the effect is as you bend tighter and tighter. Also, it will show you what happens when you 'unbend' the cable. Does the performance come back? the results are a real eye-opener (no digital pun intended) and much of what you have been led to believe isn't completely true!

Transmission characteristics of passive components such as insertion loss, return loss, VSWR, and frequency response can severely limit overall cable distance at higher transmission speeds. This is especially true with 3Gbps transmission requirements for digital 1080p HD signals. This seminar will discuss the effects of passive components in a typical transmission path used in a broadcast facility.
