I’m feeding 3 analog televisions off this at once and all 3 have crystal clear images with no degradation. Signal strength and clarity is maintained well, longevity to be determined, but so far so good!

Using it to provide channel 4 rf out over coax to supply signal to a couple of remote tvs. The modulator is being powered by the usb jack on the back of the dish receiver. No power supply included but they do include the cable. Picture quality is good enough for me. Quick and simple to hook up.
