I have a window mount for my truck of which I get good reception. It seems the thin cable I am using is not the best. I want to keep the window mount, but want to change to a thicker/better cable.Anyone know where I might get this set-up. I use the Larsen Tri-band antenna. When they say this size mount and this size mount I don't really know what they are talking about, don't need to buy several different ones in order to get the right size in the first place. any help greatly appreciated.
