OK, I've had it with the poor reception of the trunking system, I need an outdoor directional antenna and I am reading everything I can about what kind to get and how to install it. But I cannot find the answer to this one question - I install the antenna on the roof, I have a coaxial cable - how do you get the cable hooked up to the scanner? Do you put down through the walls into the room the scanner is at? Seriously, my cable tv I just plug into the wall connection, how the heck do you connect the cable from the antenna to the scanner in the house?
