Antenna Elevation Pattern Info Now Required in CDBS

As reported last week, the rules for distributed transmission systems require submission of antenna elevation pattern data.

After downloading the CDBS files Wednesday to create the TV Engineering Database spreadsheets at www.xmtr.com/fcc/ and the DTV Station Status report in this week's RF Report, I noticed some new tables had been added.

These new files include antenna elevation and make. Some new fields have also been added to the application database, including one for a station's network affiliation. The DTV transition database has picked up additional fields, including information on analog nightlight operation and Neilsen DMA data. Other new fields were also noticed in the site's "tv_app_indicators" and "tv_end_data" databases.

I'll be examining these new files to see if any of the data can be included in my TV Engineering Database spreadsheets. With the final analog shutdown three months away, I'd be interested in comments from readers on whether they would like to continue to see the DTV Station Status report every other week. With the DTV transition coming to a close, is it still useful? I will attempt to post the FCC TV Engineering Database spreadsheets every other week whether or not the DTV status report continues in my RF Report.
