I have 5 receiver with antenna in my 5 rooms. i want to place these 5 receivers in 1 room and distribute only coaxial cable to every room and watch separate channel every one. such as the cable operator.
You do not ask a question. If the receivers are connected to each TV with coax then it is straight forward. If they are connected with HDMI you will need to send HDMI over coax. There are adapters for this but it would be better to use an HDMI cat5e/cat6 system to send the signal. You will also need to send IR to each box without affecting the other boxes. Something like this would work http/www.amazon.com/HDmi-Extender-Over-2-CAT5E/dp/B0021AEZOY
Might not be work the expense.
