Have TV Questions? Ask a TV Technician
Hi, I'm Nathan.Sorry to hear that you're having trouble, but I'll do my best to help you. Please give me a few moments to review your details here.
Hello there please check to see if the Dish system uses a multiswitch which will allow both the satellite and cable to use the same cables that are feeding your TVs. You plug the signal from the Dish and antennas into the multiswitch.You will need to install a diplexer at each TV point to separate the signals. One to the Dish receiver input and the other to the antenna input on the receiver/TV. If the receivers provide power to the Dish then you will need a power passing diplexer.Also the Dish will need power so make sure that is taken into account.
Thank you for the reply.Your problem still exists with feeding the 222K receivers coax input since you only have one coax to each receiver. My multiswitch suggestion will solve that problem in that you can use the same Dish coax to feed a diplexer and the two outputs from the diplexer can feed the receiver LNB input and antenna input.As far as your 211Z is concerned, I would feed that TV's antenna input using the coax from the diplexer and the red yellow white or HDMI cable from the 211Z to the TV as shown below.
