You know You're an OTA Addict when...
Aliens in UFOs visit your house just to check out and admire your immense collection of various TV antennas.
You help customers in Fry's electronics pick out a better antenna than the one they were looking at, while explaining the difference between analog ERP and digital ERP, and why VHF-Hi is a major DTV issue!
You put up an outside antenna just to start a fight with your Home Owners Association, knowing they will lose outright!
You can look at an antenna on the roof and quote the manufacturer, model, and gain specs.
You seriously consider building a QBGH because you can get maybe 1 more dBi of gain, and you care less what the neighbors might think.
You have actually used "ladder twin lead" in order to get the lowest dB loss per foot!
You can remember when UHF in the USA included channel 83.
You can remember the first TV you had was black and white, full of vacuum tubes, and only received channels 2 through 13 VHF. And...if the President was on TV, then all you had left to watch was PBS!
You know all of your current local stations call letters, assigned frequency, and ERPs for DTV, and you can quote from memory what the old analog frequency and ERP was!
The signal strength button for your DTV receiver box will no longer work due to repeated pushing.
You hear someone say something about "Earl" and you think about an ariel.
