Question about how to setup the LCD HDTV?

Question

I bought a Dynex 32" Flat-Panel LCD HDTV and hook it up to a HD Antenna. Most of the digital channel's signal is at good or excellent, but everytime when a car goes by some channel's signal will became week or the signal got frozen. Besides that's a 4 story high building right at the back of my house. I wonder if I need to buy a HD receiver or what I need to do to correct this problem? Can somebody please help me, thank you!!

Answer 1

Upgrade your reciever/antenna. But a better stronger HD reciever, or get a bigger antenna to draw more signal!

(Antennas work better when they are in direct line-of-sight with the broadcaster.)
