Over the weekend I was prepared to run my new coax. I decided before hand that I wanted to mark all cables for location first. I moved my TV to each wall jack and would connect cables until I found the right one and label it. Interestingly enough I found that the one I thought was for my living room was not correct. I found it using the 9 volt battery and multi meter trick but obviously that did not work very well.....the cable may have been too long and had too much voltage drop.
Now that I have found the correct cables everything works great! I had to use my amplifier to keep some channels coming in clear but nonetheless works great!
Thanks so much for the help!
I also tried combining my cable internet signal and TV into one coax because I have a TV and modem in the same spot but this didn't work. Any products out there that can filter these frequencies or are both signals the same frequency?
