Axion ACN-5507 5-Inch Portable TFT LCD TV
Great little TV!
This little guy has a super picture. I use it camping hooked up to a boat battery. It uses only 8.5 watts of power so will run a long, long time on one charge. The speakers kind of stink but I connect a set of battery powered amplified speakers and it sounds great. P.S. as far as connecting a coax cable, you can purchase a mini-phone jack to coax adapter at Radio Shack.
