Basics of UHF Radio Communication
- The FCC assigns different broadcast communication uses to the different frequencies that make up the radio frequency spectrum. Radio communication in the UHF band is limited (in part) to "public land mobile" communications (for companies who want to use a private radio communications system to support their business operation), maritime communications, and amateur (ham) radio communications. The first thing you need to determine if you intend to use UHF radio communication is which type of broadcast communication you need.
- Generally, all forms of radio communication require a transmitter, antenna and receiver. But the specific type of transmitter, antenna and receiver you need depends upon which type of UHF radio communication you want to engage in. The radio communication equipment you use must have the capacity to transmit and receive the radio frequencies assigned to the type of radio communication you would like to do. You must also decide if you want a radio system that uses amplitude modulation (AM) or frequency modulation (FM) to encode and decode the information transmitted through radio waves. An AM UHF radio receiver, for instance, is not set up to decipher a radio signal transmitted by an FM UHF radio transmitter.
- Most forms of UHF radio communications require a license from the FCC. The process involved in acquiring a radio broadcast license varies depending upon which type of broadcast communication you're interested in. Ham operators are required to pass a test in order to obtain an amateur radio license. For this, you'll need to study. If you're looking to obtain a public land mobile (business) radio license, you'll have to gather information about your radio system before you apply for a license. For instance, you need to know the seven-character emission designator code of your radio system, the exact height of your antenna, the latitude and longitude of your antenna location and how many meters above sea level the terrain of your antenna site is. Research the requirements you need to fulfill in order to secure the type of radio license you want.
- The final step of the process before you can begin UHF radio communication is to actually apply for a license. There are some forms of UHF radio communications that do not require a license; it all depends on which UHF radio frequency channel you are broadcasting on. For example, you are allowed to broadcast on the assigned FRS (Family Radio Service) radio frequency channels 8 through 14 without a license as long as the radio system you're using is an FCC-certified FRS unit.
