Mohu Leaf Antennahaven't tried one of these but unless you do your camping in areas that are in very close proximity to TV transmission towers I wouldn't waste my money.
a TV transmission signal is RF....radio frequency...and is, generally, line-of-sight. we're camping in relatively small (as in height above ground) metallic or fiberglass boxes in campgrounds and parks in, usually, rural areas, surrounded by trees, hills, etc. many RVers are having enough problems getting a good signal using an amplified antenna that is elevated above the camper. why would an antenna located inside that camper deliver a better signal to the TV receiver? if you live in an apartment in the city or even a close-in suburb and don't have/can't erect an outdoor antenna then the Mohu Leaf antenna might be the answer otherwise I'd take a pass.
