The two antennas are not comparable to each other in my book

Had the ATI HDTV card with the antenna you mentioned and was unable to receive very many channel’s in my area.

I eventually I return the unit and bought an OTA receiver with cm 4228 antenna and rotor

Now receive just about all the channels on the HDTV channel map from this fine forum.

I almost never experience any dropouts in signal as long as the antenna is pointed in the right direction.
