good points zin.
a yagi or super yagi has much better gain than a stick, I am an amateur radio op, and built a breakdown yagi for camping and search and rescue work. The boxes on the wall and flat things and rabbit ears have very little difference in gain because of the form factor, despite their marketing.
If the signals for your area are directional, the EZ-HD will be much much better than an omni-directional antenna like the boxes/ rabbit ears. spend a few min aiming it with a compass.
our major broadcasters were about 180 degrees out so we approximated aiming it parallel to a line between the 2 and got a lot of channels despite our terrain and foothills between us and each of the broadcast areas. boulder to denver/ boulder to ft. collins.
