when the analog to digital TV format became effective, I purchased a small digital portable TV for hurricane season... it is rechargable and 12v capable, but with the single telescoping antenna, picked up only 5 channels..... to increase the reception, I purchased a UHF/VHF HD "rabbit ear" antenna (Zenith)...just received it...it doubled the channels to 11 and much better reception... something you might look into if you have a similar setup...I live about 35miles from the xmtrs...
