Marsand StaffMarsand, INC. is situated in Alvarado, TX, 25 miles south of Fort Worth along the access road for Interstate 35W. The Marsand building is 14,000 square feet with 3,200 square feet of office space. The facility is able to accommodate Digital Studio pre-assembly and is stocked with RF components and spectrum, network and DTV analyzers. A portable proof package is available to go on site and perform extensive troubleshooting and alignment besides the transmitter Proof of Performance for both NTSC and Digital systems. MARSAND, INC. owns and operates all of the required test equipment.

Broadcast Engineering Experience

Marsand has been contracted to provide fully turnkey installations for numerous television stations. This included designing, budgeting, purchasing and installation for mainly full power UHF stations and a few VHF stations. In most cases this was done on a group scale with multiple projects overlapping each other. The studio and transmitter sites were researched and located. The engineering portions were generated for the FCC Applications for Construction Permit. FAA Aeronautical Studies were submitted and approved. Towers were specified and designed in conjunction with structural engineers. Tower crews were contracted and supervised to erect mainly tall towers 1200 ft. to 2000 ft. tall. Building construction was both specified and contracted for studios and transmitter. Studio and transmitter equipment was purchased, installed and commissioned. Transmission line, waveguide and antennas were purchased, installed and matched using a network analyzer. A full Proof of Performance and License to Cover applications were completed.

Matthew Sanderford, P.E., has over 35 years of transmitter and studio troubleshooting experience. Over the years, he has been involved in several innovations on the RF side of broadcasting. Having pioneered the conversion of UHF transmitters from integral cavity to external cavity, wideband klystrons, he has successfully converted several RCA and Harris installations. He was one of the first to use the AutoCAD software to accurately place RF systems in 3-D to reduce installation time in the field. Recently he has been involved with HCJeffries Tower Co. in erecting a 1000 ft. tower in 11 days using special structural designs and a helicopter to do the lifts. Marsand has built two stations to date using only a helicopter to do the lifts. Marsand also has contracts to consult for twenty-eight stations – providing phone support and emergency onsite service for the transmitter plant.

The Digital Studio Facility

To date, Marsand. has designed and installed three digital studios in McAllen, Laredo and Odessa, TX. Equipment layout and wiring schematics were integrated into the architectural plans using the broadcast industry standard VidCAD program. Built upon the architectural standard AutoCAD program, the use of VidCAD files facilitated ease of collaboration with the building architects and builders. Visualization of the project allowed for problems to be anticipated and corrected ahead of time and changes to be made easily by all parties involved.

The Digital Transmission Facility

Marsand brings a depth of experience to both the planning as well as the installation and technical sides of broadcasting. Marsand has thus been able to contribute to the digital conversion of more than twenty-eight stations and is currently supervising the digital conversion for three group owners and one PBS station. The total number of these stations is twenty. Over the past 8 years, Marsand 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 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, 25 sites have been completed.
