=) go to a cable guy, ask him for a cable
we literally have 100's of these 30-50ft cables laying in our trucks, and (yes they are as good as, if not better than monster.. After all , cable companies dont want customers *****ing about poor signal, like they do EVERY SINGLE DAY ALL DAY LONG lol...)
you'll be fine with your 30$ cable, as long as its the right length,
