It's no wonder that many Americans are still confused about the conversion from analog to digital TV service, which began yesterday and is due to wrap up on June 12. Even the news media is confused. For example, an AP article on the transition included the following bit of misinformation:
In addition, many households will find that they need new antennas. Digital signals generally come in better than analog ones, but they are not received well by some older antennas.
This makes a blank screen appear to be the antenna's fault. Not so. And it could scare some people into wasting money on new "digital" antennas. A radio wave is a radio wave -- whether it carries an analog or digital TV signal. So the old antenna picks up the new signal just as well -- in fact identically -- as it picks up the new signal.
