i have a tv in my truck. it used an analog signal so i installed a dtv converter box. i have tried many different antennas, rabbit ears, amplified antenna but i lose the signal as soon as i start moving. sitting still the signal strength is 87%, but when i start driving it goes down to 0%. my analog signal worked fine while driving. someone who has it working please tell me what you used for an antenna. this is a new problem not many people have discovered yet.
