I tried two different GE boosted antennas from Wally World and while both of them improved the signal strength according to my converter box indicator, they could not pull in more channels when hooked to the new digital TV. My new TV does not have a signal strength indicator of its own. Even getting an 80% signal on the box isn't enough for a picture on the new TV.
I have added a link to the antenna that I am ordering. It can be used either indoors or outdoors if I have to go that way. I hope it will bring in enough to get the job done.
According to the internet maps I am in a pretty strong area for a signal but am equally and centrally located from the towers and not very close to any of them.
I called RCA about my new TV and they told me that any new digital TV needs a stronger signal than a converter box needs to produce a picture. New is not always better, easier, cheaper, or more fun!
