![]() ![]() Since the UHF band covers a much larger range of frequencies than VHF, 1/4-wave antennas can range anywhere from 3 to 6 inches in length, so using the proper length antenna is important. (Example: A 200 MHz wave has a wavelength of about 6', so a ¼-wave antenna length would need to be approximately 18".) For VHF Applications, an antenna anywhere from 14–18 inches is perfectly appropriate as a 1/4-wave antenna. This antenna is one-quarter the size of the desired frequency's wavelength. The most common types used in wireless audio systems are 1/4-wave and 1/2-wave omni-directional antennas, and unidirectional antennas. The size of an antenna is directly related to the wavelength of the frequency to be received. Mistakes in antenna selection, placement, or cabling can cause short range, dead spots in the performance area or low signal strength at the receiver that leads to frequent dropouts.īefore we cover placement, let's review the types of antennas you're likely to encounter in a wireless system. Many times the culprit turns out to be antenna placement. ![]() They're the ones rivaling Sherlock Holmes in the art of deductive reasoning as it relates to solving dropout mysteries. "Receiver antennas are one of the most misunderstood areas of wireless microphone operation."Ĭredit Shure's Product Support Group with that bold statement.
