Description
  • The antenna distributor can guide the antenna signal from a pair of antennas to multiple receivers in a multi-channel system. A single antenna distribution host can connect up to 8 antenna channel ports.
  • The distributor amplifies the RF signal to compensate for attenuation during the distribution process.
  • External 5A switch power supply, capable of providing four 12V DC outputs for wireless receivers.
