OTA HDTV newbie (1 Viewer)

[Jim Williams]

I just got a Samsung SIR-T151 (used) and I've noticed a couple of things. First, my reception is much much better at night. During the day I get lots of dropouts and pixellation but none at night. Second, when it is windy my reception is much poorer with lots of dropouts. Is this normal or coincidental?

BTW, I realize that there is no HD broadcast during the day, I am just curious why the reception is poorer during the day and when it is windy.

It could be because at night signals are more likely to bounce off the ionosphere and back down to Earth than be absorbed like they are when the sun is out, giving more potential signal. Also, at night there might be less sources of external intereference in your neighborhood.

I can't imagine why wind would make a difference other than if your antenna was loose and blowing back and forth off-axis to the broadcast tower.

Wind could shake a loose antenna, but more likely it's blowing tree branches or something else near the antenna and causing multipath. Another possibility is loose antenna cabling.

I forgot to mention that I am using a Silver Sensor.
