Live in an apartment and can't mess around inside the walls. When I had digital cable installed, the tech only hooked up the main TV since that is the only room with an outlet. Since then, I've added a cable modem, and the guy who installed that just ran the cable along the baseboard/doorframes all the way to the computer. Since that seemed to work fine, I now want to make a long cable-run from the outlet to a second tv in the bedroom (the cable modem installer put in a three way splitter). So, after measuring the length I ended up with roughly 68' from the outlet to the second tv. Add a few feet for flexibility, and a 75' cable should do the job. Unfortunately, radio shack only sells 50' and 100' pre-terminated cables, no 75'. I know nothing about making cables--is it worth considering buying just the cable and cutting/crimping it myself? What tools would I need, and what price would be reasonable for that length plus the connectors? Alternatively, would it matter if I had an extra 25' of cable left in a coil under some furniture? Finally, will I look like an idiot if I have the cable guy come back at some later date to install a second digital receiver on the bedroom tv, and he sees my "amateur" cable run? Thanks!
