Query: Wireless reciever means no more cable & sat boxes for little used TV's

RF Link AVS-5813 Wireless Audio/Video Receiver (5.8 GHz)Works great. You can send one signal to as many receivers(I have 3) as you need in the house.The Good: enables you to send a signal from one tv to another. Strong signal reception. Small and unobtrusive. $80 per receiver means in a year means for the 1st year it costs $7 per unit.The Bad: Won't transmit an HD signal. $80 per receiver means in a year means for the 1st year it costs $7 per unit.Bottom Line: Buy it
