I live in a fairly high signal area (TVFool shows all stations as green) and they are all located within about a +/- 5 degree spread.
I get a few too many annoying drops outs, particularly when the weather is bad.
An outside antenna is not practical, so I tried a non-amplified 'silver sensor' type antenna. It does not work any better than rabbit ears or even a random length of wire. To confirm sufficient signal strength, I added an inline 20 dB attenuator, and performance was roughly the same. It took 26 dB of attenuation before I noticed any degradation (a couple stations dropped out). I had very similar results with both an Insignia NS-DXA1 and an RCA DTA-800B1.
I assume then that the annoying drop outs must be the result of multipath. (Are there any other issues that can cause this problem?)
Does anyone have any experience using a 'Smart Antenna' and are they effective in solving multipath problems? Are there any models out there other than the RCA ANT1500?
