You’ve probably heard that after midnight Feb. 17, 2009, America’s TV sets will go digital. That means that if you have an older (analog) set that uses rooftop or indoor antennae (such as rabbit ears), it won’t be able to receive the new digital signals. (Some TVs purchased after 2005 may have digital tuners that can receive the new signals, and TVs manufactured after March 2007 were required to have digital tuners, so check the set’s instruction manual or call the manufacturer.) 

This change will not affect TV sets connected to cable, satellite or fiber-optic services, although the older analog sets hooked up to cable eventually may need digital units or pay higher cable fees.

The benefits of digital TV are clearer pictures, improved sound and better closed-captioning services. The switch will also free up much of the airwaves (capacity has been shrinking) for public safety and wireless services. 

If your set isn’t connected to cable and you can’t afford to buy a new TV with a digital tuner, you must buy a digital converter box before next February to continue getting reception.

Discount coupons. The federal government has instituted a coupon program to help people defray the cost of a converter box. The coupons are worth $40 each toward the cost of a converter box, and most major retailers sell the boxes from $40 to $70 each. The coupons expire within three months after receiving them.

To get the coupons, click on www.dtv2009.gov or call 888/388-2009. There are no free options to make the transition. Note: Even though some low-power TV stations may make the transition after Feb. 17, it’s best to apply for the coupons between now and March 31, 2009, because after that date the coupons will no longer be available. Please share this information with a friend or relative who may need it.
