When these coaxial cables are connected to an antenna, signal strength is amplified significantly. Should you need to make the signal strength stronger, you can opt to connect receivers to an antenna provided it is compatible with coaxial cables. By optimizing a wireless mic or other transmitter devices with the same frequency channels, users are able to produce clear audio thanks to an uninterrupted signal and minimal signal interferences. In the United States, most wireless systems operate within the Ultra High Frequency (UHF) spectrum, which is around 470 to 608 MHz. Channels differ depending on the location, so it’s best practice to place transmitters in the same location as the receivers. The receivers should have a dial that will allow you to adjust the bar levels of these two signals until you reach the channel with the lowest amount of interference. Although there are mics that are able to optimize this for you, it’s still good to know how you can do this yourself.įirst, you must look at the receiver’s screen, which should show you two bars representing signal strength and volume. To avoid any interference from other frequencies in the area, like radio frequencies, TV frequencies, or frequencies from a nearby device, users should be able to know the optimal frequency band in their location and systems.
