This is a wireless receiver for a 2.4 GHz receiver that is transmitting locally. The receiver/transmitter are very directional, but once you have it tuned in, it looks great. Beats the hell out of running wires across the house for security cameras, or other uses. You can connect it to a TV with RCA cables, or via coax. I have wiring for both if needed. Over coax, it transmits on channels 3 or 4 only. I no longer have the transmitter, so this unit is no good to me. And video transmitter at 2.4 GHz can be received by this, however.I’m asking $1 for this receiver. Call 316.444.0690 or email if interested.
