The Digital Transmission
Facility
MARSAND,
INC. brings a depth of experience to both the planning as well
as the installation and technical sides of broadcasting. Over the past
8 years, MARSAND, INC. has led the process of tower
inspections and modifications, building planning and electrical specification
in preparation for the DTV build-out. Budgets have been developed and
implemented. MARSAND, INC. performed the engineering
studies to maximize DTV coverage for each of the stations. FCC filings
were submitted from this office and approved. And, where applicable,
“DTV ready” equipment has been purchased and installed to
replace damaged or outdated equipment. To date, the following sites
have been completed:
