Question: What is antenna power?
Answer: Wireless microphone systems can be difficult to design, set up and operate. There are many things to take into consideration. For example, one has to determine the right system to match the intended use and budget. Also, it is important to determine the proper frequency/frequencies to use, which in this day of ever-shrinking spectrum can be a challenge, especially when using multiple systems. In many applications it may be necessary to remote-mount the antenna some distance away from the receiver as well as split or combine antenna signals to create a more stable RF link. Due to the complexity of some setups it is often a good idea to seek the expertise of an experienced systems integrator or audio sound professional.
On many wireless receivers and antenna distribution systems is a feature called “Antenna Power.” Antenna power is 12V DC that travels up the coax antenna cable to power integrated circuits built into certain devices like powered antennas, such as the ATW-A54P, in-line RF boosters, such as the ATW-B80WB, antenna splitters, such as the ATW-49SP, and combiners, such as the ATW-49CB. These devices utilize active electronics to compensate for cable loss in receive applications. Please note that a radio frequency signal attenuates as it passes through coaxial cables. Devices such as signal amplifiers, antenna splitters and combiners are designed to compensate for that loss.
