Why? Good sensitivity, no directional selectivity.
HD is ALL or NONE: if you get a signal, you have it, very clear; if you do
not get a signal, you don't have it.
2. Why expensive HD antenna not good? Directional selectivity, you cannot
get all channels.
3. Why antenna with an amplifier not good? Actually it is not needed. The
signal is digitial. If you are not getting a good signal in your area,
getting the singal AND noise 100 times bigger at the sa | a9

OK, take it back. Do you need to turn the antenna to get a good perception
for different channel?
Check out sports or news, not movies or recorded programs like Desperate
Housewife. If you still could not see the difference, get a better HDTV.
