Spectrum Repack — Your RF Plant and What to Consider
Martyn Horspool, Product Manager, TV Transmission
Repacking of the UHF TV band to free up valuable spectrum for new wireless services has the potential to impact every TV station in the USA. Changing the channel of a transmission facility will require careful planning and execution to be successful. This paper highlights some of the more important aspects of such a change, including transmitter, RF plant, transmission line and antenna.
Furthermore, many ATSC transmitters in service today are either obsolete, or discontinued models that cannot be readily channel changed. It is even more important to note that older transmission equipment is often very inefficient when compared to modern state of the art designs. Depending on several factors, this may be an excellent opportunity to consider replacement of the transmitter along with other items in the RF chain. A tool for examining transmitter Total Cost of Ownership (TCO) and Return on Investment (ROI) is discussed and examples based on typical transmitters in service today are presented. A brief discussion on planning for future ATSC 3.0 operation is also addressed.
