98.100.198.100
I live in an apt building on the second of 3 floors. I have NO direct line of sight to the transmitter towers. I get a lot of dropouts on over the air digital TV. (the signal strength fluctuates from 98% down to 40%/25% and back very quickly, and the TV screen goes blank under about 50%. Different times of day, and different indoor antenna positions just change which channels do it!!
I have tried adding major mass under the antenna (2 old VPI 'bricks: steel plates in a wooden box) and it helps stop the dropouts.
I want to know why?
I still loose a few channels depending on the antenna position, but at least the dropouts have gone away (for the most part)

that works too.
coil the steel cables around your antenna.
At my dad's house, dropouts are fairly sporadic and only affect certain channels, but when they do occur, they seem to coincide with planes flying overhead. (He lives on a hill near SFO.) Maybe those VPI bricks are somehow blocking whatever interference that planes might be emitting???
My dad's using a VERY old (50's-era) TV antenna for his digital TV reception and it seems to do a decent job, but I'm hoping to find something better and more 'modern' for him....

you can try using a powered antenna booster. I bought one years ago I think I had to order it from radio shack. I plugged mine in by the tv. I have a house antenna so I dont know if it would help much for indoor. but I think it would help. back then they were around $20 to $25

Don't know. What kind of indoor antenna? Most of the ones designed for indoors, such as the pretty-good-for-what-it-is Sensor type, don't have a great reflector. I'm wondering if the metal in the bricks is acting like a half-assed reflector to some extent... The reflector makes a huge difference when done properly. I recommend trying a small outdoor antenna if you're still annoyed, used indoors I mean, they can be quite small and not too ugly.
For an experiment, try adjusting the antenna spacing above the bricks.
