Digital TV Reception Experimenting

posted Friday, 7 August 2009

I started investigating digital TV reception at a rural area and documented it in a previous article.  Yesterday I did some experimenting at various times with a Jensen TV931 amplified antenna connected to a Magnavox digital TV tuner to analog converter.  The following table summarizes the results:

 1  Rotation of 0 degrees corresponds with front of antenna (logo side) facing north
 2  Channel 2 was coming in choppy before I rescanned for channels, but did not show up in the scanned channels

 

Interestingly, putting this antenna outside during the day did not help like last time, although the location of on the roof was different this time.  Last time I had it mounted further away from the trailer near the ground.  I'd like to do this experimentation again with some different outside locations.
