This is my second Mirabox HDMI Coax Extender. The previous one had sound that faded in and out and lasted about a year before the sound went completely out on the transmitter portion. This one has a similar problem -- the sound fades in and out. I'm afraid the sound will go completely out shortly. The picture is excellent. This set up is exactly what I need since I have existing coax running to my patio TV. Wish it wouldn't have the sound problems. Would also like Mirabox to offer just the transmitter (sender); then, it could be replaced without having to purchase the entire package.
