Thanks for pointing that out,
I never considered that some cable grades are not suitable for RF. I know what is best to use at home for A/V, but have never considered what is best for RF. My problem is that the prime location is a wall with no electric, I pulled the USB trick when my office was upstairs, and was able to move the CM15A closer to a central location by running a USB line, but we still had to move around the house inorder to get the unit recieve the remote signals. I am wondering what type of antenna I should put in the wall and if I do the f-connector mod, can I connect the new antenna to the CM15A. I want to run my CM15A with an antenna loctated 15-20 feet away. Using f-connectors, the appropriate coax, and antenna, that should be possible.
