Operation
Notes
• This product is designed for combining receive antennas for wireless microphone receivers and is not recommended for use with transmitters.
• Use standard 50Ω coaxial cable.
• An In-Line Amplier may be used to compensate for losses associated with long runs of coaxial cable. Enable DC power when using ampliers.
• Adjust the RF input attenuation levels if signals exceed normal ranges of wireless microphone receivers.
